The Application of Renewable Energy Sources in the Electric Power System of Isla de la Juventud

Currently, energy production based on renewable energy sources (RES) is being widely introduced, since it is considered an environmentally friendly type of production. However, its variable, intermittent and unpredictable nature means that continuous energy production is not guaranteed. Energy storage systems can be used to smooth the power output schedule of RES-based power plants. The energy storage system parameters are chosen taking into account technical and economic constraints. The article presents the factors influencing the increase in the share of solar power plants in the structure of power system generating capacities. The solar power plants application conditions were analyzed, and the analysis results have shown the need of using an energy storage system for control of power system frequency and ensure the required quality of electricity.
