With the increase in the power grid capacities of renewable sources of energy (RSE) and the implementation of measures and means to compensate for the dependence of their generation on natural conditions, the role and importance of RSE in electric power systems (EPS) is changing. RSE are real opportunity to decentralize electricity generation and provide power supply systems with a reliable source of energy. It is shown that it is advisable to do this in the form of local electric power systems (LEPS), which operate in normal modes in parallel with the EPS as balancing groups, and in extreme conditions are able to operate in isolation in an autonomous mode. To ensure the reliability and quality of electricity supply to electricity consumers in to LEPS offered to integrate RSE and energy storage systems (ESS) in the form of separate microgrid (MG). To ensure technical and economic efficiency, MGs are combined into an intelligent control system based on SMART Grid principles. This allows for more rational use of MG resources, effective interaction with the distribution grid, and the use of EES as RSE reserve in the process of balancing the LEPS. The research offers a hierarchical structure of the intellectual system of LEPS as consisting of individual agents designed to respond to the variable current states of the LEPS and form collective actions to ensure reliable power supply to consumers. Autonomous agents make control decisions and form a multiagent system. LEPS with intelligent electric grids structured in this way can avoid losing renewable sources of energy during centralized power supply constraints and fully use their advantages together with energy storage systems to ensure reliable power supply to consumers.
