Abstract: The chapter analyzes the schedules of electricity consumption and generation in the electricity network with renewable energy sources (RES) as an opportunity to improve the electricity balance in it. It is shown that in order to achieve a positive effect from the introduction of RES into the electric grid, a balance of electricity generation and consumption must be ensured in it. To do this, first of all, the values of the optimal installed power of RES are determined to coordinate the generation and electricity consumption schedules, and the principles of consumption management in the electric network are formed. In order to increase the stability of power supply systems, it is proposed to use electric power accumulators, which, if there is a certain energy reserve in the accumulator, can be used in case of an insufficient amount of RES generation. An algorithm for the method of matching the generation schedules of the PV power plants and the electric load of the network has been developed. At the same time, the cost of displacement of consumption power is estimated, for which a corresponding indicator has been developed. Since the quality of power supply depends not only on the balance of active power, but also reactive power, RES with inverter energy conversion devices are considered as a means of regulating reactive power in the electrical network in order to maintain the voltage within acceptable limits.
