This article considers the solution to the problem of ensuring reliable and efficient electricity supply for consumers using sources of energy storage. It is noted that energy storage can help improve the overall quality of electricity supply, especially when the share of power from alternative energy sources increases. The use of accumulators in low-voltage networks is described in order to obtain the maximum profit of households from renewable energy sources and storage stations for balancing the network and improving its stability. The possibility of compensating fluctuations from renewable energy sources by releasing power at peak times and charging from the network at the time of minimum is indicated. The simulation results of a network with a nominal voltage of 20 kV with a generalized source of renewable energy in the form of a solar power plant and a storage battery are demonstrated. Benefits of using data sources such as energy management, backup power, load balancing, frequency regulation, voltage maintenance and grid stabilization have been identified. The work demonstrates the relevance of using sources of energy storage to ensure sustainable and efficient electricity supply to consumers.
