The principles of building a traditional balance of production and consumption of electricity in the electric power system are outlined and the difficulties of using such a balance to analyze current trends in the development of the UES of Ukraine are shown. A power differential bal-ance in the electric power system is proposed, in which the total demand for power change is determined by the algebraic sum of changes in the power consumption and generation of power units of nuclear power plants, thermal power plants and renewable energy sources, and the demand is covered by the algebraic sum of changes in the power of generation of power units of hydroelectric power stations, hydro power plants and thermal power plants. The power dif-ferential balance was used to analyze current trends in the development of the UES of Ukraine in the conditions of intensive commissioning of renewable energy generating capacities. The analysis based on dispatch schedules for hourly production and consumption of electricity for 2017—2019.
