Комплексні енегрогенеруючі вузли в об'єднаній енергетичній системі

Abstract

The state of development of solar and wind power plants in Ukraine and their impact on the unified power system are analysed. Feasibility of combination of solar and wind power plants in integrated power generating node to reduce the impact of weather conditions on the amount of generated energy is studied. There are is proposed mathematical models of the nodes power plants that take into account the change of meteorological factors and their influence on its generation graph. According to the simulation results obtained ratio of installed capacity of solar and wind power plants to the maximum load, that providing daily energy balance taking into account the climatic conditions of Ukraine in different seasons of year. For ensuring instant power balance in node it is offered to use energy accumulation, the algorithm of a storage control system functioning is developed. The expediency of using pumped storage power plant for energy accumulation in a power node is shown.
