Локальні електроенергетичні системи на основі відновлюваних джерел енергії

Abstract

The paper shows the possibility of forming local electric power systems (LES) based on renewable energy sources (RES) as balancing groups in the electric power system (EES), which can maintain operational efficiency and provide power supply to consumers in an autonomous mode. The sources of electricity in the LES are small hydroelectric power plants (MHEP), photovoltaic and wind power plants (FES, VES), the production of which is unstable due to dependence on natural conditions. Therefore, the structure of a RES-based LES provides an energy storage system, the reserves of which are sufficient to compensate for the instability of generation and balancing of the regime. In the LES, existing maneuvering power, electrochemical storage, hydrogen technologies and biogas plants are used as a reserve.
