The article offers evaluation of the potential of renewable energy in improving the energy security of decentralized power supply systems and solving the problems of their development. The authors proposed a complex of indicative indicators with introduction of renewable energy sources as part of separate indicators, which allows us to research the energy security problems of regional decentralized energy systems of power supply. In the rationale for each indicator the place of renewable energy sources in aspects of resource security, the level of reliability of autonomous power supply systems, environmental and other positions of energy security have been shown. The proposed module of indicators with introduction of renewable energy includes a science-based list of criteria, methods and tools for their evaluation with the focus of measures to ensure energy security by means of integrating into autonomous power supply systems of renewable energy plants. 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

The prosumer can use energy storage to enhance the benefits of electricity trading by transferring buy and sell points. Improving energy efficiency is not considered from the standpoint of the entire system, but from an individual prosumer and in conditions of difficult-to-predict wind power generation. This work aims to optimize the prosumer’s electrical complex by developing a method for adapting the base of heuristic rules of the prosumer control to its parameters and climatic conditions. A method for adaptation control rules using swarm intelligence algorithms is proposed. The computer simulation has shown that the use of swarm algorithms makes it possible to increase the economic efficiency of managing the prosumer’s energy storage system by 2–4 times compared to the control rules manually constructed by an expert. It is shown that the proposed method makes it possible to automate the construction of the base of control rules

The article aims to develop a set of objective criteria for assessing the state of energy security in decentralised remote regions of the north, Arctic zones and autonomous energy supply complexes. The authors assessed the potential of renewable energetics, which determines the effectiveness of decentralised energy complexes based on renewable energy sources, in improving the energy security of such entities. The indicators for assessing the energy security of research objects were developed on the basis of an analysis of the ratio of the most significant threats, as well as territorial and situational factors of the autonomous energy of the north and Arctic zones. A study of the security of the research objects allowed the development of a set of criteria for territorial segments and autonomous electrification objects, forming an objective assessment of the energy security of isolated hard-to-reach areas. An analysis of the possibilities of renewable energy sources in achieving certain positions (resource sufficiency, environmental acceptability, technological attainability and reliability) of the energy security of the considered level was conducted. Groups of properties and processes within the territorial framework of a decentralised region, separated by the directions of monitoring the energy security of local energy zones are proposed as objects of indicative analysis. The differentiation of the developed criteria by the levels of the energy zone and decentralised energy complex allowed consideration of all the specific features of these objects and cover the factors of mutual influence with accompanying systems in the formation of the state of energy security. When considering a possible option for the participation of renewable energy sources in the structural and resource provision of autonomous electricity supply, it was found that such diversification will affect both the improvement of some criteria of energy security of the considered level, as well as the deterioration of others.
