Using the example of the Burzyanskaya SES (Republic of Bashkortostan), operating in an autonomous mode from the power grid, the possibilities of using renewable energy sources (RES) and energy storage systems (ESS) are described. The tasks of ESS in the power system are considered: stabilization of frequency and voltage, optimization of load, reduction of electricity losses. An analysis of the economic efficiency of the implementation of ESS is carried out.
