Implication of the EU Countries’ Energy Policy Concerning Scenarios Affecting the Air Quality Improvement

Energy policy has a significant impact on the state of the environment and, therefore, on residents’ health and life expectancy, especially in highly urbanized areas. Reducing emissions is currently one of the necessary actions that must be taken at the scale of individual countries to ensure sustainable development. The article aims to identify the best ways to shape energy policy by evaluating development scenarios for air protection and their environmental impact. The realization of the goal is based on the data included in three groups: (1) Economic factors, Health factors, and Demographic factors; (2) Clima-e related economic losses, Renewable Energy sources in electricity, heating, and cooling, Premature deaths due to exposure to fine particulate matter (PM2.5), Health impacts of air pollution, Population change; (3) Demographic balance and crude rates at the national level, GDP per capita in purchasing power PPS, GDP, and principal components; covering 36 EU countries in 2019 and 2021. The study proposes an advanced methodology for assessing development strategies by integrating the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Bayesian networks (BN) and incorporating them into a multicriteria decision-making (MCDM) support system. The TOPSIS model based on BN allowed for the illustration of the features of many criteria and the identification of relationships between scenarios, allowing for selecting the best way to develop energy policy. The results showed a 60.39% chance of achieving success in extending the life of residents by five years. At the same time, the most favorable development path was the scenario promoting activities aimed at reducing air pollution by introducing renewable energy sources to produce energy used for lighting and preparing domestic hot water urban areas. By presenting possible scenarios and the probability of success, it is possible to achieve the goal of practical energy policy at the level of the country and individual European cities and also by extending the life of city inhabitants, as presented by the authors in this study.

Construction of the structure of rural electric networks taking into account the availability of renewable sources of electricity

It is noted that although the share of renewable electricity sources continues to grow and develop rapidly, the industry still faces many challenges, including how to continue to reduce electricity losses and annualized costs, improve operation and maintenance efficiency, maintain grid stability, ensure safety and reliability of the power supply system containing renewable sources of electrical energy. It is shown that an effective solution to these problems is possible only on the basis of the analysis of the prospects for the development of local electric power systems that contain renewable sources of electric energy, the development of technical and organizational support mechanisms that will contribute to the construction of modern system (schematic) solutions. It is proposed to apply the potential surface method for building the optimal structure of the rural electrical network during its design and modernization in the presence of renewable sources of electrical energy, which allows optimizing the structure of the network from the point of view of electrical energy losses and reducing annualized costs. The algorithm for forming the structure of power supply systems is described, which implements the simultaneous solution of the tasks of determining the number of load nodes, distributing electrical receivers between them, determining the design of power sources, taking into account the discreteness of the design of system elements. The results of numerical modeling based on the proposed algorithm are presented on the example of solving the problem of reconstruction of a section of the rural electricity network.

Obtaining the maximum power from the source using step-up and step-down type pulse regulators that work on battery

Introduction. Pulse regulators are widely used to match the output resistance of the source with the load resistance in order to ensure the possibility of taking maximum power when the value of the load resistance changes. Problem. In the case of using non-traditional and renewable sources of electrical energy, for a more uniform supply of energy to the load, a battery is often connected to the output of the pulse regulator, which works in buffer mode. In such cases, the load for the pulse regulator will be the battery itself, and the role of the source load will be performed by the input resistance of the regulator. To ensure the mode of operation of the pulse regulator, in which the maximum power will be transmitted from the source to the load, it is necessary to know the regulating characteristics of the regulator. There are works that analyze the regulating characteristics of step-up and step-down pulse regulators, which are used to match the load with the output resistance of the source. At the same time, for the same purpose, pulse regulators of the step-up and step-down type can be used. Goal. The purpose of the work is to analyze the features of the operation of step-up and step-down type pulse regulators in the mode of maximum power transmission from the source to the battery, as well as to determine the conditions under which it is possible and appropriate to use such regulators for the specified purpose. Methodology. The regulating characteristics of step-up and step-down type pulse regulators with sequential and parallel switching on of the controlled key were determined and analyzed, taking into account the presence of a battery at their output. Results. It is shown that the transfer of energy from the source to the battery is possible only under certain modes of operation of the regulator, which depend on the type of regulator, as well as the amount of voltage on the battery. The conditions under which it is possible to draw the maximum power from the source are determined. Originality. Since the output resistance of the source and the load resistance are of the same order in the maximum power selection mode, the internal resistance of the power source was taken into account when determining the regulating characteristics of the regulators. Practical value. The obtained results made it possible to formulate practical recommendations for a justified choice of the regulator’s operating modes, depending on its type and the value of voltage on the battery.

FEATURES OF THE CONFIGURATION OF CONTROL SYSTEMS FOR PHOTOVOLTAIC INVERTERS

Today, the issue of energy supply and the implementation of ecological systems of electricity generation is relevant, including in the agricultural sector of the economy. This issue is important not only at the state level, but also at the level of the world community. The world's leading countries are actively implementing world-leading technologies for the decarbonization of the energy sector. One of the options for the introduction of alternative and renewable energy sources in the agricultural sector of the economy of the leading countries of the world is the use of photovoltaic systems. The use of modern sources of electrical energy is also inherent in the transport industry. One of the options for such implementation is the use of photovoltaic systems in electrical networks of electric transport and auxiliary systems and infrastructure complexes. Also, attention should be paid to modern global trends in the development of distributed energy systems, which are characterized to a large extent by the use of new progressive developments in power electronics. Also, attention should be paid to modern world trends in the development of distributed energy systems, which are characterized by the use of new progressive developments in power electronics, which are already used in various areas of the economy [1]. Therefore, network converters of electrical energy, which are operated as part of distributed generation systems and as part of complexes based on renewable sources of electrical energy, must meet the parameters of the network, and their control system must be adaptive to stochastic modes of network operation and modes of generation by renewable sources of electric energy. Meanwhile, attention should be paid to the synchronization of three-phase electrical energy converters with the electrical network to which they are connected, which must be ensured by a system for regulating their operation. It should be noted that the structures of control systems of network converters have a significant difference from the structures of control systems of autonomous converters, which directly concerns inverters. This state of affairs is connected with the peculiarity of the functioning of network inverters. Since the specified converters have a modulated sinusoidal voltage using PWM to form in accordance with the parameters of the network to which they are connected. Therefore, the issue of synthesizing a mathematical method that will simplify the development of an automatic control system and also optimize the computing resources of the power converter control controller for photovoltaic systems is relevant. On the basis of analytical data, it is possible to predict with full confidence the post-war development of Ukraine's economy based on the introduction of modern progressive technologies in the field of energy. To date, the sustainable development of the economic and energy component of Ukraine's economy is postponed. Meanwhile, electric power generation systems remain a priority in the context of not only implementation into existing power supply systems, but also relevant in the context of national energy security. The paper considers the use of Park's transformation in the development of control systems for network inverters of photovoltaic systems. The results of the research, which were conducted on inverters whose control systems were built using the proposed mathematical apparatus, confirm high control accuracy and efficiency, without spending a large amount of computing resources of the microcontroller. The proposed approach to building control systems for inverters of photovoltaic systems will allow to increase the efficiency of the operation of photovoltaic systems, which will make them more economically attractive for implementation in the agricultural sector of the economy.

Energi listrik berkelanjutan: Potensi dan tantangan penyediaan energi listrik di Indonesia

Economic growth and increasing population density have an influence on the large need for electrical energy in Indonesia. The amount of energy needed is directly proportional to economic growth and population density. This condition could threaten energy security in Indonesia if all stakeholders still depend on non-renewable energy. Coal, oil, and natural gas, which are continuously exploited for generating electricity, will eventually run out and will no longer be able to meet Indonesia's electrical energy needs. Apart from that, the use of non-renewable energy also has a negative impact on the environment. Indonesia is a country that is rich in renewable energy sources that can be used as a source of energy for generating electricity, but there are still obstacles in processing and using them, so they are not optimal. This paper aims to analyze the potential and challenges of providing electrical energy in Indonesia. The method used is a descriptive method using primary and secondary data and literature studies. The results of this study show that the potential for renewable energy that can be processed and developed for electricity generation is quite large, namely from energy sources originating from geothermal, hydropower, mini-hydro and micro-hydro, bioenergy, solar power, wind energy, and ocean waves. The survey results show that 52% of the public agree with the use of renewable energy, and 43% agree with the use of nuclear energy as a source of renewable electrical energy. The reason for choosing nuclear energy is the reliability of the energy supply. A strategy for developing renewable electrical energy can be formulated based on the opportunities and challenges currently faced to achieve energy security in Indonesia. Efforts to develop renewable electrical energy need to be carried out with the cooperation of all relevant stakeholders so that the sustainability of electrical energy in Indonesia can be realized.

Successful policies also take into account real market factors and barriers, the need for simplicity and accountability, minimum costs and profitability levels.

Controlled power distributed photovoltaic system using solar energy forecast

The use of renewable energy sources to supply electricity in customer grids is a current practise in developed countries and, particularly, in the case of distributed solar energy generation grids. Even though, the environmental benefits of the practise drive to economic incentives to increase the renewable energies. However, because of the unsteady behaviour of the renewable electric energy sources [1], as wind energy and solar photovoltaic production, the increment in the use of these sources produces severe fluctuations in the electric grids. Then, their electric supply to the electric grid is limited and at the same time, an accurate renewable energy production forecast is required. In this work, the feasibility of a new approach to reduce this problem is tested by the application (on a yearly basis) of a simulator of a production-storage controlled system, namely FOTOV, to be applied in the design of a photovoltaic (PV) installation

Calculation of the economic and environmental efficiency of introducing advanced technologies in the energy supply of buildings

This article discusses the use of advanced cogeneration technologies at existing combined heat and power plants, regulating the supply of thermal energy in a building using an individual heating point. For Uzbekistan, an urgent problem is the serious study of the use of energysaving technologies, in particular in the heat supply systems, for the efficient use of investments. The achieved effect of reducing specific energy consumption for the production and consumption of thermal energy to the level of world standards will ensure the energy and environmental security of the country, which urgently requires accelerating the implementation of these projects. The search for large and small projects for the technical and technological renewal of production to ensure the competitiveness of products, as well as the means and sources for this should first become the most important task and responsibility of the manager and engineering staff of each heat supply enterprise. The article provides calculations on the basis of which the payback, investment, efficiency of measures in the field of renewable energy sources for electricity and heat supply are determined, as well as the calculation of thermal energy savings when installing an individual heating point.

РОЗПОДІЛЕНЕ РЕГУЛЮВАННЯ НАПРУГИ РОЗПОДІЛЬЧОЇ ЕЛЕКТРОМЕРЕЖІ З ВІДНОВЛЮВАНИМИ ДЖЕРЕЛАМИ ЕЛЕКТРОЕНЕРГІЇ

The problems of distributed voltage control in electrical grids (EGs) with renewable sources of electric energy with converter-interfaced generation (CIG). It is proposed to control the EGs modes by controlling the reactive power of converter-interfaced generation. It is proposed to use the mean square deviation of the voltage in the converter inter-faced generation (CIG) installation nodes as the criterion of the target function. The extremum seeking control method was used to solve the problem of dynamic optimization with daily changes in the parameters of the electric network, namely the loads and active power of renewable sources. The examples provided have shown the improvement of the voltage in the EG at different levels of reactive power generation limitation according to the norms of the standard EN50549-1:2019. The optimal values of the average daily value of the rms deviation of the voltage of the ieee33 test EM were obtained with a significant penetration of the RES power. Bibl. 12, fig. 4, table. Keywords.: distributed voltage control, converter interfaced generation, extremum seeking control method.

PRINCIPLES OF APPLICATION OF ALTERNATIVE ENERGY SOURCES IN REGIONS WITH LIMITED DRINKING WATER RESOURCES

The unsatisfactory ecological state of water resources indicates, first of all, the problems of pollution and depletion of water resources and their relevance today. The lack of an optimal principle of management and responsibility for the state of surface sources of drinking water supply has led to the fact that industrial facilities, which, depending on their technological processes, determine the state of the surface source of drinking water, are located in the territory of the same regions, and the production and consumption of drinking water from of this source occurs on the territory of other regions, which complicates the settlement of control issues at the regional level. Therefore, solving the task of preparing drinking water of the required quality at drinking water treatment stations is a strategically important task in the conditions of a significant anthropogenic factor. This issue has become especially relevant in recent years on the territory of Ukraine in connection with the armed conflict, which has turned into a full-scale armed conflict on the territory of Ukraine. Today, these issues concern the south-eastern regions especially acutely. Meanwhile, it should be noted that the long-term operation of water supply systems without a capital replacement of communications, the lack of modernization of treatment facilities, or their absence at all, the consequences of irresponsible economic activity that led to the pollution of surface water became the prerequisite for a difficult situation with water supply of standardized quality. Of particular concern in connection with chemical and bacteriological pollution is the state of water supply for the rural population, which in most cases uses water from underground water sources for drinking purposes. A quarter of the villages and towns of Ukraine use the services of centralized domestic drinking water supply, and more than 60% of the population of most regions in Ukraine consume water from wells, the nitrate content of which is 1.5–30 times higher than the standard level. So, taking into account the fact that fresh water resources on Earth are distributed extremely unevenly, and arid or partially arid regions of the world include 40% of the landmass, which use only 2% of the world's water reserves, the issue of the introduction of modern water supply systems and the modernization of existing ones with the use of modern technologies is gaining more and more importance. According to the conclusions of scientists and the analysis of statistical data, it is possible to predict the development of the economy of Ukraine based on the introduction of hydrogen energy. But regardless of today's realities and a number of obstacles in the development of Ukraine, it is worth paying attention to urgent problems in the country that require urgent solutions, on which national security depends. Taking into account the fact that renewable energy sources are currently widely implemented in Ukraine and the world, and taking into account the problem of water supply as a global problem and local problems of a regional scale in the territory of Ukraine, it will be relevant in the future to use the indicated capacities to obtain certain volumes of suitable water, in accordance with sanitary standards, for use by the population. The proposed approach of using the capacities of renewable sources of electric energy for the needs of the functioning of systems for obtaining water suitable, in accordance with sanitary standards, for use by the population. The introduction of renewable energy sources into the system of obtaining water suitable, in accordance with sanitary standards, for use by the population should provide an opportunity to expand the functional capabilities of existing installations and increase their efficiency. This approach also aims to attract the attention of investors and reduce the ecological burden on the environment.

Features of the work of pulse regulators in the maximum power transmission mode, with the presence of an accumulator at their output

Introduction. For the efficient use of non-traditional and renewable sources of electrical energy, it is necessary to ensure their operation at the maximum power point, which is possible if the load resistance is equal to the output resistance of the source. To match the load resistance with the output impedance of the source, a matching switching regulator is connected between the source and the load. Very often, the amount of energy received from such sources depends on external conditions. To ensure a uniform supply of electrical energy to the load, a battery operating in buffer mode is connected at the output of the switching regulator. Problem. In this case, the load of the switching regulator is the battery, and the input impedance of the regulator will perform the role of the load of the power source. This resistance depends on the voltage of the battery, the type of switching regulator and its mode of operation. In such cases, the maximum power extraction mode from the source can be provided by selecting the appropriate operating mode of the switching regulator. The aim of the work is to analyze the conditions and determine the modes under which the transfer of the maximum possible amount of electrical energy from the source to the battery is ensured, as well as the features of the switching regulator in these modes. Methods. For this purpose, the regulating characteristics of step-up and step-down switching regulators were determined and analyzed, taking into account the presence of an accumulator at their output. Taking into account that in the maximum power transmission mode, the output resistance of the source and the load resistance are of the same order of magnitude, when determining the regulating characteristics, the internal resistance of the source was taken into account. Results. As a result of the analysis of the obtained regulating characteristics, the conditions were determined under which the transfer of energy from the source to the battery is ensured, and the parameters of the operating mode of the switching regulator were determined, under which the maximum power will be taken from the source of electrical energy. Novelty. The originality of the work is the consideration of the internal resistance of the source of electrical energy in determining the regulating characteristics of pulse regulators. Practical value. The obtained results made it possible to indicate the appropriate range of battery voltages for different types of pulse regulators, as well as to give practical recommendations for choosing the mode of operation of the pulse regulator depending on its type, as well as the amount of voltage on the battery.

This study aims to analyze the causality relationship between CO2 emissions and electricity generations in the 10 most populous countries. This study uses secondary data from the British Petroleum (BP) annual report from 2000-2021. The data analysis method uses Pairwise Dumitrescu-Hurlin Panel causality analysis, carried out by stationarity and cointegration tests. The results of the analysis state that there is a bidirectional relationship that influences each other between CO2 emissions and electricity generations. The implication of this research is the need for countries to prepare for renewable sources of electrical energy to be able to reduce CO2 emissions, especially those sourced from fossil energy.

Analysis Of Output Power Control Of Mini On Grid Plts Without Kwh Exim In Fajrul Iman Patumbak Modern Islamic Boarding School

The decreasing of world’s supply of fossil energy caused by the human need for energy continues to increase. As a result, energy prices will be more expensive. Solar cells that utilize solar energy are a source of renewable electrical energy (RE). The use of solar cells to generate electricity can be used to reduce the burden of electricity bills anywhere as in Islamic boarding schools. The burden of electricity bills at the Fajrul Iman Patumbak Modern Islamic Boarding School, Deli Serdang Regency is quite a burden on Islamic boarding school expenses. To reduce the burden of spending on electricity bills at Islamic boarding schools, solar cells and control equipment are installed so that they can generate electricity. The control system is installed using an on-grid system, the electricity generated can be directly used by the Islamic boarding school during the day and will reduce some of the power absorbed/taken from PLN. After this service is carried out, the cost of spending on Islamic boarding schools has decreased.

Automatic PV Array Reconfiguration under Partial Shading Conditions

Photovoltaic (PV) arrays have been recognized as one of the main clean renewable sources of electrical energy. In practice, PV arrays are subject to unavoidable non-uniform partial shading (PS) due to clouds, buildings, dust, etc. PS causes the hot spot problem, mismatch losses, and output power degradation. A widely used approach to mitigate the effect of PS is dynamic reconfiguration, where, the interconnection of PV panels is modified according to the shading condition to achieve maximum output. Dynamic reconfiguration techniques use sensors, a programmable controller, and a switch matrix for optimal operation. However, they have drawbacks such as system complexity and scalability issues. For instance, reducing the number of switches limits the flexibility of the reconfiguration algorithm. In this paper, an automatic dynamic reconfiguration scheme is proposed in which PV panel irradiation activity controls the interconnection of switches, without the need for a programmable controller. A modular building block is proposed from which easily scalable PV arrays can be constructed in a hierarchical manner. Experimental and analytic results have verified the effectiveness of the proposed reconfiguration scheme.

The Cost of Islamic Boarding School Electricity Bills is Lowered by Installing Solar Cells on Grid Limiters

The world's supply of fossil energy is currently decreasing, and in time it will be scarce, while the human need for energy continues to increase. Solar cells that utilize solar energy are a source of renewable electrical energy (EBT). The burden of electricity bills at the Fajrul Iman Patumbak Modern Islamic Boarding School, Deli Serdang Regency is quite a burden on Islamic boarding school expenses. To reduce the burden of spending on electricity bills at Islamic boarding schools, solar cells and control equipment are installed so that they can generate electricity. After this service is carried out, the cost of spending on Islamic boarding schools has decreased. From this decrease, other Islamic boarding schools who know about this program are excited to utilize solar cells as a source of electric power. In the end, this program became a pilot for Islamic boarding schools that used EBT. All of these hopes can be seen in the dedication video that has been broadcast on the YouTube channel.

Analysis method for the design of long submarine cables

The recent push for renewable electrical energy sources has resulted in a significant increase in the installation of the offshore wind farms. These farms become much bigger than their earlier counterparts and the generated power is much larger. This puts additional performance requirements on the export cables. Long submarine export cables are not only subjected to changing laying conditions along the route, including depth and seabed material variations, but also the loading patterns vary significantly over time. Additionally, applied reactive power compensation measures and the time-dependent grid situation change the distribution of the current along the route. These unique features of long submarine power cables necessitate a new type of approach to their design and construction optimization. This paper introduces a new approach for ampacity calculations of long submarine power cables. As the ampacity calculations form a basis for the design of a cable route, it is of paramount importance that they are performed as accurately as possible. The approach can be applied to general-purpose circuit solvers, and this paper describes how to implement it using the ATP-EMTP software, which is extended to the consideration of concurrent electrical and thermal effects. The approach permits considering all the important local and time-dependent parameters of the analysis simultaneously. In particular, the approach allows simultaneous analysis of the varying laying conditions along the route including changes in the depth of burial and thermal resistivity of the soil together with the temporal variations of the cable loading. Additionally, current characteristics in long AC cable conductors are strongly affected by the reactive power flow, which in turn depends on the location of the reactive power compensation, the reactive power demand for grid operation, and the wind farm voltage reactive power control strategy. Such analysis cannot be performed with any existing analytical tool. Also, numerical tools cannot handle such problems because a 3-dimensional time-dependent analysis of a cable route which is 100 km long would encounter convergence problems as the size of such model would be prohibitive. Hence, at present, the proposed approach is the only one available to solve this complex electro-thermal problem. Several numerical examples illustrate an application of the proposed methodology.

The role of renewable energy sources in residential electricity prices: A club convergence analysis across selected European countries

ABSTRACT This research analyses the convergence of residential electricity prices in 22 European countries between 1995 and 2019. The findings reveal the existence of two sub-convergent clubs of residential electricity prices. Half of the countries studied belong to the club with higher residential electricity prices, while the other half belong to the lower-price club. Household income increases the probability of belonging to the club of lower residential electricity prices. An increase in heating degree days decreases the probability of belonging to the club of lower residential electricity prices. A similar effect is observed for the price of non-renewable energy sources used in electricity production. Further, although a country’s likelihood of belonging to the club of lower residential electricity prices diminishes with a rise in the share of renewable electricity production, the converse pattern is obtained at the residential level, such that residential renewable electricity share has a beneficial effect. Our findings suggest that households have benefitted in paying lower prices for renewable sourced electricity. Therefore, this research indicates that ongoing clean energy initiatives and the availability of affordable substitutes for conventionally generated electricity are being realized to a certain extent, improving electricity markets for the countries we analysed.

CONTROL SYSTEM OF THE ELECTRICAL COMPLEX OF STREET LIGHTING

To date, taking into account the strategies for the development of control systems and the active introduction of distributed generation sources into various spheres of the world economy, including those based on renewable sources of electrical energy, hybrid systems of artificial outdoor lighting controlled by intelligent control systems are being developed. The paper proposes an approach to the construction of an external lighting control system on city highways and public places. Regulation of external lighting is carried out by adjusting the luminous flux of lamps, and the sources of luminous flux are the lamps with which they are equipped. But not all types of lamps are suitable for adjusting the smooth change of light flux. If there is a communication channel between the network of lamps equipped with EIDs and the dispatching service, it is possible to transmit information about the state of operation of EIDs and the performance of lamps in order to detect deviations in the operation of EIDs and lamps that need to be replaced. In accordance with the given schedule for changing the level of external lighting, the KD software sends a command to change the level of light flux on specific lamps. The control unit transmits incoming information (a command) to the control unit, which, together with the lamp control channel connected to it, forms a local lighting control network. The decentralized outdoor lighting control system provides for the absence of a control room, server, server access devices, as well as the Internet as a means of communication, executive equipment of the substation and replacement of the PUS with the APUS, as well as the presence of service personnel who will service the equipment of the APUS substation, KOP and SC, as a result of the lack of feedback from the APUS to the OP, i.e. the maintenance of the PS is carried out directly by maintenance and programming specialists Thus, a scheme for decentralized management of outdoor lighting on city highways and public places was proposed.
