A Two-Stage Flexibility-Oriented Stochastic Energy Management Strategy for Multi-Microgrids Considering Interaction With Gas Grid

Introduction of renewable energy sources (RESs) and independently operated multi-microgrid (MMG) systems have led to new issues in the management of power systems. In this context, uncertainty associated with RESs as well as intense ramps inflicted on the network called system flexibility constraints have raised new challenges in power systems. The new condition necessitates the implementation of novel frameworks that enable local system operators to efficiently manage the available resources to cope with the flexibility-ramp constraints. Moreover, the new framework should facilitate energy management in a system with an MMG structure considering uncertainty of RESs. Consequently, in this article, we aim to provide a novel framework that composes of a two-level stochastic optimization procedure to optimize the energy management in an MMG, considering uncertainty of RESs as well as grid flexibility constraints. In the proposed scheme, resource scheduling in microgrids (MGs) is conducted in the first level by their control units, while the second-level procedure focuses on the coordination of MGs, considering flexibility constraints. Furthermore, interaction with gas grid as a potential flexible resource is optimized in the second-level procedure. Finally, the provided flexibility-oriented management scheme is implemented to schedule the local resources in a three-MG test system, considering flexibility constraints.

BEELINE: BilevEl dEcomposition aLgorithm for synthesis of Industrial eNergy systEms

Energy transition to a more sustainable basis is the most significant and complex challenge facing industry. On most industrial sites, the largest single energy user is the utility system that produces the heat and power necessary for the site. The heavy reliance of current utility systems on fossil fuels and the requirement of strategic measures to ensure a sustainable future has prompted researchers to explore different energy sources, technologies and pathways for evolving existing systems to a sustainable basis for future utility systems. Whether based on renewable or non-renewable energy sources, it is essential to minimize energy demand and mitigate emissions. The present work focuses on developing cost-effective solutions for the synthesis of process utility systems, considering site-wide energy integration. This will provide a platform in future work for the efficient introduction of renewable energy sources in the transition to sustainable systems. Utility system performance is generally determined by system configuration and operational load. Steam mains selection, in terms of pressures and superheating have a critical role in the utility system performance and site energy integration. Therefore, the synthesis of energy-efficient utility systems involves optimizing the configuration of utility components and number and operating conditions of steam mains simultaneously. Due to nonlinearities and non-convexities from underlying physics and binary decisions involved, the resulting Mixed-Integer Non-Linear Problem (MINLP) presents challenges for advanced state-of-art solvers to solve real-world problems. In past work, a number of important practical issues have been oversimplified in order to make the solution tractable. However, the oversimplifications also lead to misleading results. In this research, a mathematical formulation for simultaneous optimization of comprehensive utility system configurations and operating conditions is for the first time combined with more realistic steam system configurations and operating conditions to represent the utility systems. Its framework is constructed via a bilevel decomposition algorithm based on piecewise MILP relaxation, McCormick relaxation, and linearization of steam properties. In addition, the solution pool feature of the CPLEX solver is incorporated to enhance the performance and convergence of the algorithm. This work presents the fundamental problem formulation that has not been sufficiently addressed previously. Indeed, this methodology sets out the basis for synthesizing energy-efficient utility systems for the future and allows for many energy conversion technologies and sources to be added to the framework that have previously not been possible to include.

Directions of Application of Phasor Measurement Units for Control and Monitoring of Modern Power Systems: A State-of-the-Art Review

The development of modern power systems is directly related to changes in the traditional principles of management, planning, and monitoring of electrical modes. The mass introduction of renewable energy sources and control devices based on power electronics components contributes to changing the nature of the flow of transient and quasi-established electrical modes. In this area, the problem arises of conducting a more accurate and rapid assessment of the parameters of the electrical regime using synchronized vector measurement devices. The paper presents an extensive meta-analysis of the modern applications of phasor measurement units (PMUs) for monitoring, emergency management and protection of power systems. As a result, promising research directions, the advantages and disadvantages of the existing approaches to emergency management, condition assessment, and relay protection based on PMUs are identified.

SPECIAL FEATURES OF ENERGY TRANSITION IN ASIAN COUNTRIES

The current stage of development of the world energy industry is taking place in line with the fourth industrial revolution, characterized by the changing ways of life and the introduction of new technologies based on R&D. Environmental pollution has reached a large scale, and as a result it has become necessary to change the structure of modern fuel and energy balance in favor of renewable and non-traditional energy sources. Asian countries vary widely in terms of the level of economic development, making it difficult to create an integrated energy market in Asia. A typology of countries according to the level of economic development was elaborated on the basis of a multi-scale analysis using traditional methods of economic geography. In total these countries rank first in the world in terms of greenhouse gas emissions, accounting for almost 60% of pollutants released into the environment. The fuel and energy balance of Asian countries is characterized by a high proportion of coal, which contributes to the large-scale environment pollution. In accordance with international practice, the countries of the continent adopted energy programs aimed at lesser emissions by reducing the share of coal and switching to low-carbon energy sources. The energy transition can take place primarily in the leading Asian countries that have necessary financial resources. Most Asian countries are at the early stages of industrialization, and the energy transition is almost impossible at this stage because they use energy-intensive industrial technologies. The urgent need to stop climate change comes into conflict with rising energy consumption. Asia has become the world’s leader in energy consumption, as it takes place not only in industry, but also in the utility sector, because 4.2 billion people, or more than 50% of the world’s urban population, live in cities. China has become a leader in the introduction of renewable energy sources, the country has developed and implements new environmental standards that will achieve carbon neutrality by 2060 through the accelerated commissioning of new zero-emission power plants. The rejection of coal could aggravate socio-economic problemsof Asia because of its high share in the fuel and energy balance and the large number of people employed in the industry. In line with the sustainable development goals, the Asian countries try to introduce renewable energy sources based on the local comparative advantages.

GLOBAL TRENDS IN IMPLEMENTATION OF RENEWABLE ENERGY SOURCES AND FEATURES OF THEIR IMPLEMENTATION DURING THE RECOVERY OF UKRAINE'S ECONOMY

The world trends in the introduction of renewable energy sources (RES) and the peculiarities of their implementation during the recovery of the economy of Ukraine are considered.
 It is shown that the world energy sector is undergoing a fundamental transformation, therefore it is necessary to develop a new energy security paradigm that will ensure reliability and availability while simultaneously reducing emissions, and green energy is an unconditional global trend of the coming decades. It has been determined that diversifying our energy supply by investing in RES is one of the promising ways to protect ourselves from the risks of energy dependence. The state and effectiveness of RES use at the beginning of the third decade of the 21st century is analysed (according to the Renewable Energy Policy Network for the 21st Century and The International Renewable Energy Agency).
 Consolidated energy and climate statistics for 2021 according to the document World Energy & Climate Statistics - Yearbook 2022 (World energy and climate statistics - yearbook 2022) are provided, comparing statistical data of individual countries and Ukraine. The analysis of the effectiveness of the implementation of various types of RES at the level of world markets and Ukraine for the period 2010–2021 and 2020–2021 was evaluated using the average estimated cost of electricity production throughout the life cycle of these power plants (LCOE).
 When considering the European policy in the field of RES and energy efficiency, the schedule of the development of renewable energy in the EU and the characteristics of the REPowerEU plan, developed by the European Commission, are presented, which outlines the course for reducing the consumption of oil and gas in general, as well as the introduction and use of "green" energy sources. A detailed description of the development of renewable energy in Ukraine in 2020-2021, as well as world trends in RES, which will affect the reconstruction of the Ukrainian economy, is provided. The impact of the full-scale war unleashed by Russia against Ukraine on the operation of renewable energy in Ukraine is shown, the main directions of the recovery of our country in the post-war period with the use of RES are highlighted.

Decarbonization of the national energy industry in the context of the latest geopolitical crisis

Aim. The presente study aims to evaluate the relevance of decarbonization of the Russian energy industry in the context of the latest crisis; to identify emerging and prospective problems; to determine their prerequisites and ways to overcome them.Tasks. The authors systematize mechanisms available before the crisis aimed at supporting the development of renewable energy sources (RES) in Russia and assess the extent of their functioning at the time of writing; determine how today’s economic challenges will affect the introduction of new low-carbon energy sources; evaluate the possibility of engaging the population in the decarbonization of the energy industry through an in-depth interview of an expert group.Methods. This study uses analysis of the regulatory framework and other industry sources and in-depth interview of an expert group to identify negative trends in the further reduction of the carbon footprint in the energy industry and investigate the prerequisites for the engagement of the Russian population in decarbonization.Results. On the way to reducing the carbon footprint in the energy sector, new renewable energy facilities will face the first difficulties. The postponement of the 2022 selection of RES projects for one year and the provision of a non-penalized two-year delay in the introduction of RES have actually shifted the commissioning of new capacities by three years. The departure of localized producers of wind turbines contributes to a shift in the timing and a decrease in the volume of commissioning of new wind farms in Russia. The traditional energy sector faces similar problems due to the withdrawal of major gas turbine manufacturers from the market. A survey of the representatives of the expert community (industry specialists) showed that experts as household consumers of electric and thermal energy consider the problem of ecology to be still relevant. They are generally positive about the further development of low-carbon generation and are ready to support the decarbonization of the energy industry, but with no more than a 10-20 % surcharge to the existing tariff.Conclusions. Compliance with the global trend of energy transition for Russia presents multiple challenges in the context of the latest crisis. Withdrawal of the manufacturers of high-tech equipment from the market, reduction of green energy exports, and expiration of green international certificates have significantly slowed the pace of decarbonization. However, a survey of the expert community of industry specialists shows that the development of environmentally responsible consumption of electric and thermal energy in Russia can attract green investment in the country’s energy sector from the population.

Spatial analysis of renewable energy sources in Lviv region

The introduction of renewable energy sources makes it possible to expand the possibilities of development of branches of the national economy, in particular heat energy, to accelerate economic growth and reduce the release of greenhouse gases into the environment. Spatial analysis of renewable energy sources contributes to their effective use and allows for planning the local development of renewable energy. In this article, a spatial analysis of renewable energy sources in the Lviv region, such as wind energy, solar radiation, fuel wood, agricultural animal manure, and sewage sludge, is performed. It was established that the most promising district in terms of the availability of renewable energy sources is the Stryi district, since the amount of solar radiation and the amount of forest land in it are higher than the same indicators for other districts, in addition, the amount of sewage sludge is also one of the highest in the region. For the possibility of increasing the total share of renewable energy sources, the districts of the region can cooperate with other districts of both Lviv region and neighboring regions.

Prospects for use of man-made disturbed lands in mining regions for the location of renewable energy sources facilities

This article describes the prospects for use of man-made disturbed lands of mining regions, which for a number of reasons are not subject to recultivation, in the context of the effective use of renewable energy sources. The use of renewable energy sources is considered, first of all, to satisfy energy needs, but taking into account their environmental value and renewability. It is shown the importance of decentralization of power supply sources for consumers, which can be achieved through the use of renewable energy sources. The article provides a brief structure of Ukraine's energy consumption. The main obstacles that stand in the way of the development of renewable energy sources and improvement of energy efficiency in Ukraine are analyzed. As one of the perspective directions for the introduction of renewable energy sources, the use of wind power plants is considered. The main advantages of wind energy are listed. Formulas for calculating the power of a wind power plant are provided. The gross potential, technical potential and economic potential of the implementation of wind power plants are considered. The coefficient of wind energy utilization, which depends on the wind speed, is given. The paper gives a comparative assessment of existing types of wind turbines – with a horizontal and a vertical axis of rotation. It has been proved that vertical axis wind power plans are more effective for implementation. The vertical axis wind power plans have their advantages. It is recommended to use vertical axis wind power plans with using of a magnetic levitation. This makes vertical axis wind turbines the most efficient. Due to the use of wind generators with a vertical axis of rotation of a turbine with a magnetic-levitating bearing, in the conditions of Kryvbas, vertical wind power plants can produce electricity more than 7 times more than traditional (horizontal) ones. It has been proven that the amount of generated electricity increases with the height of the wind turbine location. The article examines the ecological advantages of placing wind power plans on man-made disturbed lands of mining regions.

The problem of climate change in the energy policy of the Biden administration

The U.S. energy policy has undergone profound changes in recent years. The introduction of new technologies in the energy sector, the widespread use of renewable energy sources allowed the United States to reduce its dependence on the import of hydrocarbon resources and increase their export, which, in turn, influenced the evolution of the energy strategy at the beginning of the 21st century. The economic, financial and technological advantages allow the U.S. to influence the global energy market. Since the Obama administration, there have been discussions in the United States regarding the gradual replacement of traditional hydrocarbon resources (oil, gas, coal) with renewable energy sources. "Traditionalists" tend to believe that the U.S. is still committed to the traditional principles of energy policy: diversifying the sources of oil and gas imports, promoting free trade in global energy, the need to maintain special relations with oil and gas exporting countries. Supporters of the intensive introduction of renewable energy sources are betting on the replacement of traditional energy resources with solar panels, batteries, and wind generation. The Trump's energy policy was aimed at the global energy dominance of the United States by increasing oil and gas production and exporting liquefied natural gas (LNG) to the EU and other regions of the world. Under The Joe Biden administration the U.S. government has announced a plan for "clean" energy: reducing carbon emissions and actively transitioning the American economy to renewable energy sources in the context of the global climate agenda The author comes to the conclusion that the radical energy policy of the Joseph Biden administration aimed at solving climate problems is based on excessive expectations of the possible results of the widespread use of renewable energy sources, while the U.S. economy is still largely depending on fossil fuels, especially oil. The United States do not have a comprehensive energy strategy that simultaneously aims to ensure climate and energy security with avoiding direct confrontation and conflict with other countries.

Current state and directions of transformation of the world energy market

The research is devoted to the current state and directions of transformation of the world energy market. It was determined that at the current stage, the global economy is going through a very uncertain moment, when the cumulative effects of adverse shocks over the past three years, in particular the COVID-19 pandemic and the Russian invasion of Ukraine, are manifesting in unpredictable ways. Economic growth to 2030 is projected to be slower than previously predicted, implying lower levels of activity in all sectors. This causes lower growth in energy demand, driving a significant change in global energy supply compared to previous projections. It is substantiated that the uncertainty regarding the price forecast of the world energy markets increases due to the uncertain recovery of the growth of the world's leading economies (USA, China, EU countries), as well as due to the energy transition to an economy with net zero emissions. It was determined that instability in the energy markets activates the transformation of national energy policies. This is evidenced by the increase in annual investments in clean energy (USA and China), the acceleration of the introduction of renewable energy sources and the efficiency improvement (EU and China), a significant increase in financing for technologies, including nuclear, with low levels of hydrogen and ammonia emissions (Japan, Korea). etc. It was concluded that taking into account the challenges faced by the global economy and the world energy system in particular, it is necessary to form a new paradigm of energy security in order to maintain reliability and availability while reducing emissions for the transition to net zero emissions scenario. National economies face the challenges of parallel reduction of fossil fuels and expansion of clean energy systems. Power generation systems need to be more responsive, and network infrastructure needs to be strengthened and digitized. This requires new technological solutions, which, in turn, require significant financial investments. Continued technological innovation and recycling are vital measures to reduce stress on critical mineral markets.

REGULATION OF THE EFFICIENCY OF THE ENERGY SECURITY SYSTEM IN THE INDUSTRY OF RENEWABLE ENERGY

The annual increase in the volume of energy resources from various renewable energy sources was also noted. The forthcoming book on the growth of the specified indicator was also noted. The countries of the world that currently occupy leading positions in the practical implementation of renewable energy sources on national markets are outlined, including the European Union, the United States of America, China, and India. The fact that energy policy formation is implemented based on the complete domination of non-traditional energy sources over the usual and established fossil and destructive forms for humanity is noted. The strengths of renewable energy sources that should be taken into account are outlined, among them: internal energy characteristics of the potential, which by their content are necessary to satisfy the needs of humanity. Experience convincingly proves that the most significant development of alternative and renewable energy sources should be expected in those countries that today are energy-dependent on fossil and traditional fuels, supplying them to other countries while having a significant external debt burden. It is this circumstance that stimulates own extraction of energy resources through the use of RES; renewable energy sources are available and have an unlimited term and reserves of their use; the economic and ecological component of replacing fossil and dangerous, high-cost energy resources with more accessible, safe resources of non-traditional origin; optimization of price policy by limiting the cost of hydrocarbon resources and minimizing unforeseen losses; complete greening of the environment through the use of environmentally friendly technologies and the use of innovative technological means of work. It has been proven that to achieve maximum efficiency from the functioning of the energy security system in the field of renewable energy sources; it is expedient to observe the following four criteria, which necessarily include: decarbonization as one of the ways to get Ukraine out of the energy crisis; development of a new Strategy for the energy sector of Ukraine in the conditions of post-war recovery; the availability of systematic energy security through the introduction of renewable energy sources are programs and sources of financing; the availability of the routine scope of the application of renewable energy sources with the use of state-market instruments for the regulation of renewable energy in Ukraine. The author's model of regulation of compliance with the efficiency of the energy security system in the practical application of renewable energy sources is proposed.

Stability Improvement of Power System with a Wind Farm by the Virtual Synchronous Generator Control of Battery

As the introduction of renewable energy sources (RESs) increases, there is a concern that the inertia and synchronizing power of power systems will decrease and the system stability will deteriorate. In particular, if a large-scale wind farm is disconnected from the grid in compliance with the grid code due to a grid fault, the entire grid may become unstable. Under such a background, this paper proposes a storage battery system which has the functions of reactive power control and virtual synchronous generator (VSG) control as well as control of system frequency fluctuations due to fluctuating output from the wind farm. In addition, a new control method is also implemented in the battery control system in order to improve the total charge/discharge efficiency of the battery by suppressing unnecessary charging and discharging. The proposed battery system is composed of multiple batteries installed at different locations and they are controlled coordinately. Effectiveness of the battery system for system stabilization is verified by simulation analyses.

Modeling of transmission capacity in reserve market considering the penetration of renewable resources

This study presents a planning model for utilizing emergency transmission capacity in the power system reserve market with renewable energy sources. To this end, first, the effects of the operation of a transmission line at higher power than rated power are described. The lifetime reduction of transmission lines caused by operation under these conditions is then measured, and finally, the price is determined based on the rate of lifetime reduction. This surplus capacity is then entered into a two-stage model of the energy and reserve market as a function of price offer, while also taking renewable energy sources into account. The numerical results of a 6-bus network indicates that the introduction of renewable energy sources reduced energy costs while increasing reserve market costs due to uncertainty. Despite the emergency capacity, such costs are reduced due to the network’s utilization of low-cost resources.

Ensembles of realistic power distribution networks

The power grid is going through significant changes with the introduction of renewable energy sources and the incorporation of smart grid technologies. These rapid advancements necessitate new models and analyses to keep up with the various emergent phenomena they induce. A major prerequisite of such work is the acquisition of well-constructed and accurate network datasets for the power grid infrastructure. In this paper, we propose a robust, scalable framework to synthesize power distribution networks that resemble their physical counterparts for a given region. We use openly available information about interdependent road and building infrastructures to construct the networks. In contrast to prior work based on network statistics, we incorporate engineering and economic constraints to create the networks. Additionally, we provide a framework to create ensembles of power distribution networks to generate multiple possible instances of the network for a given region. The comprehensive dataset consists of nodes with attributes, such as geocoordinates; type of node (residence, transformer, or substation); and edges with attributes, such as geometry, type of line (feeder lines, primary or secondary), and line parameters. For validation, we provide detailed comparisons of the generated networks with actual distribution networks. The generated datasets represent realistic test systems (as compared with standard test cases published by Institute of Electrical and Electronics Engineers (IEEE)) that can be used by network scientists to analyze complex events in power grids and to perform detailed sensitivity and statistical analyses over ensembles of networks.
