The purpose of the paper is to develop a model of balancing the processes of generation and consumption of electricity for cases of limited or insufficient information about the load on the energy system. In the absence of sufficient historical data on these processes, generalized statistics are used for modeling. This is due to the excessive requirements for the needs for backup power and energy storage systems. The subjects of the study are hybrid power systems that use traditional and renewable energy sources and have local network properties. Such systems are sensitive to variable power consumption modes that complicate current load estimation. The presence of wind and solar power plants makes it difficult to ensure a balance of power, increasing the needs for intermediate energy storage. The method of the local system study is mathematical modeling of random processes of energy consumption and generation. The source of consumption information is statistics on the work of individual consumers who have a limited need for electricity and are interested in autonomous sources. The use of dispersed generation, including the use of local solar and wind energy sources, is promising for such consumers. Data on different consumers are grouped according to the state classification of economic activities. Then the power balancing process can be regarded as a superposition of random generation and consumption processes. The proposed load representation model makes it possible to simulate real processes in such a way that the results are consistent with the available statistics. The results of the study make it possible to compare different options of the power grid for balancing and energy storage needs. Ref. 17, tabl. 1, fig. 4.
