Agent Based

In recent years, the vast penetration of renewable energy sources has introduced a large degree of uncertainty into the power system, thus leading to increased trading activity in the continuous intra-day electricity market. In this paper, we propose an agent-based modeling framework to analyze the behavior and the interactions between renewable energy sources, consumers and thermal power plants in the European Continuous Intra-day (CID) market. Additionally, we propose a novel adaptive trading strategy that can be used by the agents that participate in CID market. The agents learn how to adapt their behavior according to the arrival of new information and how to react to changing market conditions by updating their willingness to trade. A comparative analysis was performed to study the behavior of agents when they adopt the proposed strategy as opposed to other benchmark strategies. The effects of unexpected outages and information asymmetry on the market evolution and the market liquidity were also investigated.

Thermal Power Plants

It is well known that the electrical-power generation is the key factor for advances in any other industries, agriculture and level of living. In general, electrical energy can be generated by: 1) non-renewable-energy sources such as coal, natural gas, oil, and nuclear; and 2) renewable-energy sources such as hydro, wind, solar, biomass, geothermal and marine. However, the main sources for electrical-energy generation are: 1) thermal - primary coal and secondary natural gas; 2) “large” hydro and 3) nuclear. The rest of the energy sources might have visible impact just in some countries. Modern advanced thermal power plants have reached very high thermal efficiencies (55–62%). In spite of that they are still the largest emitters of carbon dioxide into atmosphere. Due to that, reliable non-fossil-fuel energy generation, such as nuclear power, becomes more and more attractive. However, current Nuclear Power Plants (NPPs) are way behind by thermal efficiency (30–42%) compared to that of advanced thermal power plants. Therefore, it is important to consider various ways to enhance thermal efficiency of NPPs. The paper presents comparison of thermodynamic cycles and layouts of modern NPPs and discusses ways to improve their thermal efficiencies.

An analysis of Ukraine’s sustainable development targets, in particular in the field of energy, resource management and environmental protection, are presented. It is shown that regional energetic is a determining factor for achieving the aims of sustainable development. Changes in the natural environment in Ukraine due to external (global) and internal (local) factors that are intertwined and overlapped can cause threats to socio-economic development. It is proved that in the areas of mining and industrial activity a multiple increase in emissions of pollutants into the environment are observed. The comparison confirmed the overall compliance of the structure of consumption of primary energy resources (solid fossil fuels, natural gas, nuclear fuel, oil and petroleum products, renewable energy sources) in Ukraine and in the European Union, shows a steaby trend to reduce the share of solid fuels and natural gas and increasing the shares of energy from renewable sources. For example, in Ukraine the shares in the production and cost of electricity in 2018 was: the nuclear power plants – 54.33 % and in the cost – 26.60 %, the thermal power – 35.95 and 59.52 %, the renewable energy sources – 9.6 and 13.88 %. The energy component must be given priority, as it is crucial for achieving of all other goals of sustainable development and harmonization of socio-economic progress. The paper systematizes the indicators of regional energy efficiency and proposes a dynamic model for the transition to sustainable energy development of the region.

Optimal Set

Higher penetration of variable renewable energy sources into the grid brings down the plant load factor of thermal power plants. However, during sudden changes in load, the thermal power plants support the grid, though at higher ramping rates and with inefficient operation. Hence, further renewable additions must be backed by battery energy storage systems to limit the ramping rate of a thermal power plant and to avoid deploying diesel generators. In this paper, battery-integrated renewable energy systems that include floating solar, bifacial rooftop, and wind energy systems are evaluated for a designated smart city in India to reduce ramping support by a thermal power plant. Two variants of adaptive-local-attractor-based quantum-behaved particle swarm optimization (ALA-QPSO) are applied for optimal sizing of battery-integrated and hybrid renewable energy sources to minimize the levelized cost of energy (LCoE), battery life cycle loss (LCL), and loss of power supply probability (LPSP). The obtained results are then compared with four variants of differential evolution. The results show that out of 427 MW of the energy potential, an optimal set of hybrid renewable energy sources containing 274 MW of rooftop PV, 99 MW of floating PV, and 60 MW of wind energy systems supported by 131 MWh of batteries results in an LPSP of 0.005%, an LCoE of 0.077 USD/kW, and an LCL of 0.0087. A sensitivity analysis of the results obtained through ALA-QPSO is performed to assess the impact of damage to batteries and unplanned load appreciation, and it is found that the optimal set results in more energy sustainability.

The general topic of this paper is to study the possibilities of using renewable energy sources to supply urban consumers electricity, consumers located in areas affected by industrial restructuring. This carries out a comprehensive study on the possibilities of using renewable energy sources in the Motru Basin area. Moreover, creation a mix capable of producing the electricity needed by the inhabitants, in household consumption and not only, is being studied. The entry of free energy market has brought about the alignment with competitive conditions and observance of pollution regulations in force, and energy production has determined retrofitting or restriction of the activity of some thermal power plants due to non-competitive costs for primary energy resources. Our country has a diversified and balanced energy mix (hydropower, nuclear energy, coal and natural gas) but it must be complemented by renewable sources (wind, solar, biomass) to provide stability and energy safety prospects.

The Future

The future of European energy is moving towards a single European electricity market and an increasing share of renewables in the overall production mix. After the expiration of governmental incentive measures, power plants based on renewable energy sources will enter the liberalized market, where electricity prices will largely depend on the production of renewable energy sources. In order to achieve the maximum possible profit of the power plant under such conditions, it is necessary to consider the possibility of investing in solutions that are less represented today, but with the prospect of being more profitable in the future. Such a solution is a solar power plant consisting of vertically placed bifacial modules whose active surfaces are oriented in the east-west direction. This configuration of the power plant can achieve higher production in periods of high prices, and thus higher profits from the sale of electricity. On the other hand, such a solution is more expensive than a standard solar power plant with monofacial modules. In this paper, a comparison of return on investment in a bifacial power plant and a monofacial power plant with existing and prospective market conditions is performed. PVsyst software was used to analyze the solar potential and production profiles of photovoltaic power plants. The influence of solar power plant production on the price of electricity was investigated on the example of Germany. Based on this research, a prognostic model of the daily price diagram on the unified European market until 2040 was formed which served for the analysis of the profitability of investments in the two considered variants of the solar power plant realization.

Energy Sources

Renewable energy sources (RES) are not limited by geologically accumulated reserves. Their use and consumption will not lead to the inevitable depletion of the Earth's reserves, and they do not pollute the environment. The main motive for the accelerated development of renewable energy in Europe, the United States and many other countries is concern for energy independence and environmental safety. Thus, the EU has adopted a program to achieve the contribution of renewable energy sources to the energy balance by 2020 up to 20%, and by 2040 – up to 40%. Renewable energy is characterized by versatility and diversity. In the list of tasks arising in the implementation of renewable energy (RE) projects (except technological and technical), there are issues of assessing the possibility and efficiency of using RES for energy supply to the regions. At the same time, it should be borne in mind that often the user is interested in comprehensive assessments for various types of energy sources. In specific regions, the most effective can be either the use of hybrid power plants, or the creation of thermal power plants using various types of renewable energy. In connection with the complexity of this problem, as well as the geographic “regionality” of renewable energy, the topic of this article becomes possible and relevant. A heat and power plant is proposed for supplying: electricity, hot water, hot air and heating, in which, together with a wind power generator, a double-circuit solar installation, a heat pump, electricity and heat accumulators are used. This installation allows to reduce the cost of heat energy by reducing material consumption and costs of equipment used, to save fossil fuel; produce electricity and supply the surplus to the state power grid; reduce heat load and environmental pollution.

Energy security and stability has become a major issue over the last few years in the whole world's economic and social development. Despite its high development and evolution of its approach to the issue of energy security, the European Union is also facing the problem of decreasing its role in reducing human impact on the climate. Energy is of essential importance for the development of any country, including Bosnia and Herzegovina. Without adequate policies in the energy sector bussines, industrial and economic progress is not possible either. However, regardless of how energy is important for the development, it is still only a mechanism for achieving an ultimate goal – sustainable economy, clean environment, high living standards, prosperity and population health. According to the official data, Bosnia and Herzegovina produces annually about 13.600 GWh (data from 2010), out of which 7.950 GWh in thermal power plants and 5.650 GWh in hydro power plants. Basic domestic energy sources in Bosnia and Herzegovina include coal and hydropower, while gas and oil are imported. This paper gives an overview of future of the European Union energy policy by 2020, together with the situation and outlooks for Bosnia and Herzegovina renewable energy sources: hydropower, wind power, solar energy, biomass and geothermal energy. The legislation of renewable sources in the Federation of BIH, as well as the European Union's legislative framework, are also presented.

Egypt is the most dynamically developing country in the region of North Africa. In the nearest future, it is expected to turn into the largest economy of Africa in terms of GDP measured by PPP and to overtake Nigeria. The leadership of Egypt considers accelerated development of the national energy complex, including electricity sector, as one of the main drivers of the economic growth. It will be based on the latest achievements of scientific and technological progress and new forms of attracting foreign direct investment, mainly concession agreements in the format of public-private partnership. This allows medium-sized companies to participate in the process of transnationalization that becomes one of its distinguishing features on the modern stage. The master plan for the development of the electric power industry until 2035 envisages the use of various traditional and renewable energy sources. It is planned to create a balanced electric power generation structure, overcoming the current bank tilt towards gasfired thermal power plants. It is expected that in the 2034/35 financial year coalfired power plants in Egypt will account for 34.0% of electricity generation, 19.4% for solar power plants (11.8% for photovoltaics and 7.6% for concentrated solar power), 19.4% for gas-fired power plants, 14.6% for wind power plants, 8.8% for nuclear power plants, 3.2% for hydro power plants and almost 0.6% for thermal power plants working on fuel oil. The objective of electricity sector’s development is the creation of an advanced branch of the economy, in which renewable energy sources and energy-efficient technologies play an important role, ensuring uninterrupted and reliable energy supply, as well as turning the country into a regional energy hub. All this will contribute not only to overcoming the crisis phenomena in the industry itself, observed since 2010s, but also to further change in the nature of the inclusion of the Egyptian economy in the system of the international division of labor, which has undergone significant changes over the past decades.
