Recreational rest and recovery zones require a daily hot water supply, and constant availability of electricity. Therefore, the need for renewable energy sources usage in the Lower Volga region is obvious and power plants with an environmentally friendly component significant in the region. An analysis of the theoretically calculated potential renewable energy makes it possible to optimistically assert that the region is promising for autonomous renewable energy source implementation. It may be noted that potential wind and solar energy, in spite of the fact that it is distributed unevenly, is sufficient to provide energy for remote rural communities and tourist facilities. An analysis was conducted on the availability of actinometric data required for heliotechnical calculations and identified areas of applicability and accuracy of the information received from various meteorological information sources.

Due to their quantitative and qualitative potential, rural areas participate to a significant degree in the achievement of the indicative targets resulting from the climatic package. Thanks to the production of biomass and, increasingly often, energy itself during the 2005–2014 period, the share of RES (renewable energy sources) in the production of primary energy grew twofold from 5.8% to 12.1%. Biomass was the main source, but since 2010 the use of wind and sun in the production of energy has been growing rapidly. Given that the costs of alternative sources for energy production (mainly electricity) are considerably higher than in case of using raw fuels, the development of this market depends on the amount of subsidies. The system applied in Poland is widely criticized because it favours large hydroelectric power plants and co-combustion, which arouses considerable environmental, technical, market and strategic controversies. Maintaining the current support system could therefore have significant implications for the structure of the market, because it is not conducive to the development of energy, based on the initiative of citizens and their communities. It remains untapped economic potential also in industrial policy and services and, in particular, in case of RES small- and micro-installations.

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.

Hot Water Supply

The study analyzed the heating system and hot water supply with  using renewable energy sources. To design an automatic control system for heating and hot water supply, which includes a solar collector, a heat pump and a centralized heating source, the following tasks were set: - study of scientific literature on the operation of renewable energy sources; - design of a structural diagram of the automation section; - design of an algorithm for controlling the heating system and hot water supply. The relevance of designing a control system for an object with a variable structure is shown. As an automation object, the system of heat supply and hot water supply with the use of renewable energy sources is considered. The possibility of sharing a heat pump, solar collectors and a centralized source of thermal energy for heating and hot water supply was explored. The technological scheme, the automation scheme, the control algorithm, the software of the complex are designed. The proposed algorithm for controlling the heating system and hot water supply realizes the cascading operation of equipment with the priority of switching on renewable sources of thermal energy to solve the problem of reducing energy consumption. The software of the developed control system and simulation of the heating and hot water supply system was implemented in the programming environment of the controller ОВЕН ПЛК160. For technical implementation, modern automatic control system devices and renewable sources of thermal energy have been selected. The management of automation tools, data collection and visualization is carried out with the help of SCADA-system WebHMI, operating in the real-time operating system. The obtained results of simulation are confirmed by the introduction and successful operation of the designed automatic control system at the municipal enterprise of the town of Yuzhniy. The joint work of renewable sources of thermal energy and boiler equipment under the management of the developed management system has proved its energy efficiency both during and outside the heating season, and it makes it possible to achieve 30% savings on heating and hot water.

Development Plans

Due to the damage to the environment and climate caused by the generation of electricity in power plants burning fossil fuels, installations generating it from renewable energy sources are constructed. Spatial development plans for communes should consider their location. In Poland, generation of electricity in photovoltaic cells, wind farms and agricultural biogas plants has the greatest development potential. Due to the nuisance to people and the environment, wind turbines and agricultural biogas plants must be located far from residential buildings. Such conditions exist in sparsely populated rural areas. The observed development of single-family housing in rural areas is the result of the search for cheap construction sites and no local spatial development plans in most areas of rural communes. Dispersed housing construction restricts the construction of wind farms and agricultural biogas plants and thus poses a threat to renewable sources of wind and biogas energy produced in agricultural biogas plants. The situation may be changed by the requirement to include in spatial development plans the needs related to the construction of installations generating electricity from renewable energy sources and the construction of micro and small biogas plants directly at the sites where waste is generated.

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.

Solid Biomass

Conventional energy sources often do not fully satisfy the needs of a modern economy, especially given the climate changes associated with them. These issues should be addressed by diversification of energy generation, including the development of renewable energy sources (RES). Solid biomass will play a major part in the process in Poland. The function of rural areas, along with a well-developed agricultural and forest economy sector, will be a key aspect in this as these areas are suitable for solid biomass acquisition in various ways. This study aimed to determine the solid biomass energy potential in the commune of Goworowo to illustrate the potential in the smallest administrative units of Poland. This research determined the environmental and natural conditions in the commune, which helped to identify the crucial usable solid biomass resources. The total energy potential of solid biomass resources in the commune of Goworowo amounted to 97,672 GJ y−1. The highest potential was accumulated in straw surplus (37,288 GJ y−1) and the lowest was in wood from roadside maintenance (113 GJ y−1). This study showed that rural areas could soon play a significant role in obtaining solid biomass, and individual communes could become spaces for the diversification of energy feedstock.

Abstract Lack of investment in the electricity sector has created a huge bottleneck in the continuous flow of energy in the market, and this will create many problems for the sustainable growth and development of modern society. The main reason for this lack of investment is the investment risk in the electricity sector. One way to reduce portfolio risk is to diversify it. This study applies the concept of portfolio optimization to demonstrate the potential for greater use of renewable energy, which reduces the risk of investing in the electricity sector. Besides, it shows that investing in renewable energies can offset the risk associated with the total input costs. These costs stem from the volatility of associated prices, including fossil fuel, capital costs, maintenance, operation and environmental costs. This case study shows that Iran can theoretically supply ~33% of its electricity demand from renewable energy sources compared to its current 15% share. This case study confirms this finding and predicts that Iran, while reducing the risk of investing in electricity supply, can achieve a renewable energy supply of ~9% with an average increase in supply costs. Sensitivity analysis further shows that with a 10% change in input cost factors, the percentage of renewable energy supply is only partially affected, but basket costs change according to the scenario of 5–32%. Finally, suggestions are made that minimize risk rather than cost, which will bring about an increase in renewable energy supply.

The smart active residential buildings play a vital role to realize intelligent energy systems by harnessing energy flexibility from loads and storage units. This is imperative to integrate higher proportions of variable renewable energy generation and implement economically attractive demand-side participation schemes. The purpose of this paper is to develop an energy management scheme for smart sustainable buildings and analyze its efficacy when subjected to variable generation, energy storage management, and flexible demand control. This work estimate the flexibility range that can be reached utilizing deferrable/controllable energy system units such as heat pump (HP) in combination with on-site renewable energy sources (RESs), namely photovoltaic (PV) panels and wind turbine (WT), and in-house thermal and electric energy storages, namely hot water storage tank (HWST) and electric battery as back up units. A detailed HP model in combination with the storage tank is developed that accounts for thermal comforts and requirements, and defrost mode. Data analytics is applied to generate demand and generation profiles, and a hybrid energy management and a HP control algorithm is developed in this work. This is to integrate all active components of a building within a single complex-set of energy management solution to be able to apply demand response (DR) signals, as well as to execute all necessary computation and evaluation. Different capacity scenarios of the HWST and battery are used to prioritize the maximum use of renewable energy and consumer comfort preferences. A flexibility range of 22.3% is achieved for the scenario with the largest HWST considered without a battery, while 10.1% in the worst-case scenario with the smallest HWST considered and the largest battery. The results show that the active management and scheduling scheme developed to combine and prioritize thermal, electrical and storage units in buildings is essential to be studied to demonstrate the adequacy of sustainable energy buildings.
