Forecasting the impact on the environment of generating sources in agricultural production

The development of rural electrification is aimed at distributed energy, i.e. availability of autonomous sources of electricity and heat generation. Generation sources can use coal, fuel oil, gas, local and alternative energy sources as fuel and energy resources. This causes additional emissions of pollutants. Prediction of negative impact on the environment depends on the quantity and quality of emissions during the operation of various types of installations that generate electric and thermal energy. The purpose of the study is to select and substantiate the most attractive method for predicting the impact on the environment of generating sources in agricultural production. The widespread introduction of distributed energy using local and renewable energy sources will significantly reduce emissions of pollutants due to a decrease in energy intensity, matching the required load with the capacity of generation sources, using the most energy efficient sources, and widespread introduction of renewable energy sources. In this regard, it is advisable to forecast the impacts by the scenario method considering the implementation of the proposed distributed power supply system. The implementation of measures developed considering the analysis of the forecast of the negative impact on the environment of generating plants in agricultural enterprises will reduce the negative impact on the environment by introducing energy-efficient technologies into the energy balance of the enterprise, as well as increase production by up to 20% and increase sustainability. rural areas.

Еconomic efficiency of implementation of passive solar systems for creation of necessary microclimate in greenhouses

The article investigates the mechanism of introduction of renewable energy sources to create the necessary microclimate in greenhouses. The organization of greenhouses and the cultivation of various types of crops is a very profitable business, in addition, useful on all sides. The existing relationship between greenhouses and energy companies is one-sided. Today, companies are asking to sign a contract for energy supply of greenhouses for five years ahead, taking into account the hourly limits of electricity. These requirements put greenhouses in an extremely difficult position, because the energy consumption of greenhouses is highly dependent on ambient temperature and weather, which is impossible to predict even a month aheadwith a high degree of probability. For indoor plants,the use of renewable energy sources is the highest priority. The purpose of the work is to propose a mechanism for the introduction of renewable energy sources to create the necessary microclimate in greenhouses and evaluate the economic efficiency of this mechanism. Based on the analysis of scientific sources, the article considers the theoretical foundations of renewable energy sources, summarizes the advantages and disadvantages of generating electricity from solar radiation. The probability and validity of the obtained results is due to the use of general scientific and special statistical methods. The study aims to propose and justify the design of a passive solar system with heataccumulators. The model of a greenhouse with closed passive solar systems is substantiated and its economic efficiency is estimated (costs for introduction of the offered complex solar installation for the enterprise of an agro-industrial complex are covered less than for 3 years that confirms economic efficiency of its introduction). To ensure favorable conditions for plant development, the energy supply system of the greenhouse complex must ensure the reliable operation of technical means for microclimate control, lighting and watering of plants. In the process of functioning of the greenhouse complex, it is influenced by environmental factors (wind speed, ambient temperature, intensity of solar radiation, length of daylight), as well as internal factors (multiplicity of air exchange, etc.), depending on which the needs change thermal and electric energy systems. This in turn affects the importance of energy efficiency indicators. The work is a completed study, which examines the scientificand technical solution of an important scientific andtechnical problem of the introduction of renewableenergy sources in greenhouses. The model of a greenhouse with closed passive solar systems is economically advantageous, so it is advisable to implement it to create the necessary microclimate in greenhouses.

A Methodological Framework for Fostering Renewable Investments on Photovoltaic in Small Italian Islands

In Italy, 19 small off-grid islands with a total resident population of about 50,000 inhabitants almost exclusively rely on carbon intensive diesel generators to produce electricity. As a consequence, high costs and greenhouse gas emissions, as well as low security of electricity supply make these islands economically and environmentally unsustainable. This paper proposes an integrated and comprehensive methodological framework for improving the sustainability of the small Italian islands through the introduction of renewable energy sources. The framework is composed of a prescriptive phase, where the renewable capacity targets to be ideally achieved and the most effective incentives for actually promoting renewable investments on photovoltaic are identified, and an assessment phase, where the effect of the incentives introduction is evaluated, providing policy recommendations for further promoting renewable investments. Results show that a relatively high renewable share can be ideally reached with low efforts in almost all the islands considered, and differentiated incentives for promoting investments are needed to account for the different geographical characteristics of each island. However, the analysis performed in the assessment phase shows that the decarbonization process is evolving very slowly and almost all the islands are far from reaching 2020 and, even more, 2030 capacity targets. The main reasons include the short time elapsed after the incentives introduction and a generalized lack of suitable sites for the deployment of photovoltaic plants, also due to the strict environmental constraints of these areas. Further actions to promote renewable development should go in the direction of fostering investments from private subjects and better harmonizing the energy and environmental objectives through a shared strategy for the enhancement of the sustainability of the island electricity systems.

The Green Deal Policy for Renewable Energy: A Bibliometric Analysis

The industry attention to the environment has been reducing lately, leading to irreversible climate change, reaching the limit of mining, and critical indicators of СО2 emissions. That is why the EU has launched a new Green Policy which includes strategic directions for energy efficiency and which is expected to restore biodiversity and slow down the pace of climate change. Thus, on December 11, 2019, there was held the presentation of the “European Green Course”, the main targets of which are to increase the level of energy saving by creating closed cycles in the economy; to minimize greenhouse gas emissions by 2050; to form biodiversity and climate neutrality. Accordingly, countries that accept the terms of the green deal policy need to review all aspects of their economy, from energy production to food consumption, from industry to transport and construction. The purpose of the article is to analyse publications in order to identify public’s awareness of radical changes in economic and ecological spheres. The article provides a bibliometric analysis of research in the field of green deal policy, energy conservation and energy efficiency through the introduction of renewable energy sources. The authors selected 337 papers which were published in 1999-2019. Scopus provided the database for analysis. By means of VOSviewer the results of bibliometric analyses were visualized in a definitions map. It allowed identifying six clusters that combine 131 terms. As a result of the research, the connection between the terms – renewable energy sources and energy saving – was revealed with the help of the constructed bibliographic map.

Design of water pumped storage systems: A sensitivity and scenario analysis for island microgrids

The growing introduction of Renewable Energy Sources (RES) in small and isolated power systems may pose several integration challenges. Typically, this results in the necessity of performing RES curtailment to preserve the stability of the network. This has adverse consequences for the environment, as the replacement is assured by fuel-fired pollutant power stations. To avoid such issues, the RES variability can be compensated with storage systems, in particular Water Pumped Storage Systems (WPSS), which are particularly relevant in island contexts. In this work, we propose a new approach to help the decision-making processes of designing WPPS that are both technical and economically feasible and include the uncertainty of design parameters. This is done by using a metaheuristic optimization method Particle Swarm Optimization that finds out the solution that maximizes the Net Present Value of the project using a model that couples the energy balance model and the economic model. It was found that the input with most impact in the NPV of the projects is the wind energy availability. It is important to mention also the impact of the uncertainty of Capital Expenditure (CAPEX), which, when increases 50% combined with a project reduced lifetime, may lead to a negative NPV. The model, with the necessary adaptations, can be used to study WPSS on similar power systems, therefore contributing to a preliminary assessment of the technical and economic viability of this type of systems.

Strengthening Competitiveness of the National Economy by Inhancing Energy Efficiency and Diversifying Energy Supply Sources in Rural Areas

The article traces the matching of the proposed approaches with the place of renewable energy in strategic planning documents in the national security of the Russian Federation

Chinese experience in implementing renewable energy sources as a possible scenario for the Krasnoyarsk Territory

Renewable energy is a rapidly developing area of the modern economy. As many experts forecast, global electricity consumption will double by 2050, while the share of renewable sources in energy generation will be 50%. For most states, the main incentives for the development of renewable energy are the ability to eliminate the consumption of fossil fuels and reduce the level of emissions of pollutants, while ensuring sustainable development of the country. At the same time, Russia, which has significant reserves of natural resources, is in no hurry to switch to the use of energy from renewable sources since it is believed that the country’s subsoil can provide it with cheap energy resources for many generations to come. Therefore, introduction of renewable energy sources that are unable to compete with traditional energy without a developed energy infrastructure and established production is impractical. In our study we try to evaluate the efficiency of the introduction of renewable energy sources in the Krasnoyarsk Territory of Russia using the example of the Chinese experience.

20kV급 방사형 MVDC 배전계통의 보호협조 운용알고리즘에 관한 연구

Recently, MVDC(medium voltage direct current) distribution system has been interested worldwide due to introduction of renewable energy sources, an increase of DC load and customer’s demands for high quality and high reliability of the power system. Although these MVDC systems have technologies to improve and modernize the performance of the distribution system with high reliability, high flexibility and high efficiency, they have faced challenges and difficulties in the early stages of research and development. In particular, since power converter devices to supply DC sources have extremely high sensitivity, protection method of the MVDC distribution system is being required in order to protect and operate the MVDC system in a stable manner. Therefore, this paper proposes operation algorithm of protection coordination in MVDC distribution system to rapidly separate fault sections by using slope characteristics of fault currents and presents prevention method for shutdown of the main power source based on the CLR(current limit resistor). And also, this paper performs modeling of 20kV MVDC distribution system which are composed of substation, main and section converter based on the PSCAD/EMTDC S/W. From the simulation results of fault characteristics the at primary and secondary side in MVDC, it is confirmed that the main converter in primary feeder cannot be shutdown due to keeping fault currents within allowable limits of main converter, if the proper capacity of the CLR is installed at secondary side of section converter. In addition, it is found that the proposed method can separate outage sections in primary feeder and minimize them, if slope ranges of fault current are properly determined at each protection section.

The main and most effective areas of renewable energy in Ukraine are wind energy, solar energy, bioenergy, hydropower, geothermal energy. Conclusions. The main modern views on the definition of “renewable energy sources” are studied. The energy strategy of Ukraine until 2035 is analyzed. The main advantages of renewable energy and its positive impact on the environment are identified. The most powerful solar power plants and wind power plants in Ukraine are listed. It is concluded that the use of renewable energy sources is environmentally friendly, modern, safe and resource efficient. Key words: renewable energy sources, solar energy, wind energy, biofuel, hydropower.

Evaluation of the optimal renewable electricity mix for Lampedusa island: The adoption of a technical and economical methodology

Worldwide, the majority of small islands not connected to the main grid is still dependent on fossil fuels. From an economic and environmental point of view, this condition is no more sustainable given the high costs for electricity generation and the high level of pollutant emissions. Furthermore, the dependence on fossil fuel represents a risk for the security of the supply of several small developing Countries since they are obliged to import those resources from foreign Countries. The introduction of renewable energy sources in small islands represents a valid solution to solve these problems. In this context, the paper investigates the case of Lampedusa, a small Italian island whose electrical power system is currently totally supplied by diesel power plants. In the paper, the authors investigate the transition toward an economically and technically feasible generating system based on solar, wind and sea wave plants, to achieve specific targets of decarbonization. Commercial technologies are adopted for the exploitation of solar and wind sources, while sea wave plants are based on an innovative device, currently under development at the University of Palermo. A mathematical model is proposed to find the optimal energy mix that can satisfy a fixed share of annual electricity production from renewables, considering the Levelized Cost of Electricity. Finally, the proposed solution is analyzed in order to check the dynamic stability of the power system. The paper shows that, for replacing the 40% of the current electricity demand of Lampedusa, an optimal energy mix comprising 1509 kW from photovoltaic plants, 2100 kW from wind turbines and 640 kW from wave energy converters is needed. In this way, the actualized cost for the electricity production could be reduced to 0.260 €/kWh from the current value of 0.282 €/kWh.

Justification for Unscheduled Maintenance of Solar Panels Used as a Power Supply for Sprinkler Machines

The modern level of agriculture is described by the introduction of renewable energy sources. New generation sprinkler machines are being put into production, in the power system of which solar panels are used. One of the factors that negatively affect the performance of solar cells in an open field is their dusting, which is formed as a result of dust storms and wind. Cleaning of the battery panels is carried out in various ways: manual, semi-automatic and automatic. Dust cleaning is included in maintenance. (Research purpose) The research purpose is to determine the conditions for performing the maintenance, which consists in cleaning solar panels in the field. (Materials and methods) Theoretical (analysis, hypothesis design), empirical (observation, testing), experimental (ascertaining experiment) methods has been used during research. (Results and discussion) The article describes an introduced parameter for estimating the level of dusting. The power loss indicator shows the ratio of the power of the dusted module to the power of the clean module. Unscheduled maintenance is affected by the distance of the solar module from the repair point, the power of the solar module, the loss from dusting, the frequency of maintenance and cost indicators. (Conclusions) It has been found the dependence of maintenance period of the solar module of the sprinkler machine on the distance to the sprinkler machine, to the point of maintenance and repair, the power loss coefficient in case of dusting of the solar module, the cost of performing maintenance, as well as the frequency of maintenance. Article describes the boundaries of the choice of operating mode of the sprinkler between unscheduled maintenance for cleaning the solar module and the acceptance of additional power of the sprinkler power supply system according to the criterion of minimum operating costs.

Indoor Environmental Quality Analysis for Optimizing Energy Consumptions Varying Air Ventilation Rates

The energy refurbishment of the existing building heritage is one of the pillars of Italian energy policy. Aiming for energy efficiency and energy saving in end uses, there are wide and diversified improvement strategies, which include interventions on the building envelope and Heating, Ventilation, and Air Conditioning (HVAC) systems, with the introduction of renewable energy sources. The research aims at evaluating the building energy consumptions and Indoor Environmental Quality (IEQ), varying the airflow rates handled by the HVAC system. A Case Study (the Aula Magna of a university building) is analysed; an in-situ monitoring campaign was carried out to evaluate the trend of some environmental parameters that are considered to be significant when varying the external airflow rates handled by the HVAC system. Additionally, dynamic simulations were carried out, with the aim of evaluating the energy savings coming from the airflow rates reduction. The results of this case study highlight the opportunity to achieve significant energy savings, with only slight variations in IEQ; a 50% reduction in airflow rate would decrease energy consumption by up to 45.2%, while increasing the carbon dioxide concentration from 545 ppm to 655 ppm, while the Particulate Matter and Total Volatile Organic Compounds increase is insignificant.

Frequency Control of Power System with Renewable Power Sources by HVDC Interconnection Line and Battery Considering Energy Balancing

Recently, introduction of renewable energy sources like wind power generation and photovoltaic power generation has been increasing from the viewpoint of environmental problems. However, renewable energy power supplies have unstable output due to the influence of weather conditions such as wind speed variations, which may cause fluctuations of voltage and frequency in the power system. This paper proposes fuzzy PD based virtual inertia control system to decrease frequency fluctuations in power system caused by fluctuating output of renewable energy sources. The proposed new method is based on the coordinated control of HVDC interconnection line and battery, and energy balancing control is also incorporated in it. Finally, it is concluded that the proposed system is very effective for suppressing the frequency fluctuations of the power system due to the large-scale wind power generation and solar power generation and also for keeping the energy balancing in the HVDC transmission line.

THE PARADIGM OF ECONOMIC ENERGY SECURITY BY ORIENTATION ON RENEWABLE ENERGY SOURCES

Introduction. The topic of renewable energy today is one of the most relevant and requires consideration from the point of view of all components of this process, namely economic, financial, environmental, technological, and others. The transition to renewable energy is already irreversible today since natural resources are depleted, fuel prices are the subject to significant fluctuations, and the stable growth of the national economy is ensured by energy security. The purpose. The purpose of the article is to analyze the volume of global energy consumption, to analyze the impact of the introduction of renewable energy sources on the development of the national economy, to ensure energy security with the depletion of hydrocarbon resources and a slight diversification of their suppliers. Results. Today the Ukrainian economy is the most energy-intensive. Unstable energy prices are a threat both to the global economy and to each country separately. Therefore, in the event of a decrease in the supply of traditional energy resources, the importing countries experience the greatest difficulties. The existing tendency in Ukraine to increase the consumption of traditional energy sources, combined with the absence of a targeted policy aimed at reducing the volume of environmental pollution, will lead to an increase in negative economic consequences. The advantage of renewable energy sources is their equal distribution throughout the country (with the exception of water resources). This feature leads to the formation of one of the main characteristics of power systems based on renewable energy sources, namely, their decentralization. It should be borne in mind that the world energy market is made up of state and non-state participants. Non-state participants are showing an upward trend. However, the state should have the greatest influence on the national energy sector. Renewable energy is an area that, in the Ukrainian context, depends on state support, namely economic and administrative incentives. The dynamics of the development of renewable energy should be combined with the balanced development of the fuel and energy sector in Ukraine. Conclusions. The process of development and transition to renewable energy needs a systematic approach. Both qualitative and quantitative approaches are needed to assess the transition to renewable energy. An effective strategy for the transition to the introduction of renewable energy technologies should be justified by economic feasibility. The transition from traditional energy to renewable sources should lead to energy security, which contributes to stable economic growth, political independence, and improving the quality of the environmental component.
