Analysis of the impact of a microgrid on the reliability of the power system

The paper presents an analysis of the structure of installed capacity and the role of small and micro hydroelectric power plants in covering electrical loads and the stability of the power system. As part of the study of the structure of production and installed power, an analysis of the state of micro-, small hydropower has been carried out taking into account their technical characteristics and parameters and the potential of electric power generation by such hydroelectric power stations has been evaluated. The operation shows the possibility of covering electrical loads in peak operation modes. Obtained results of analysis can be used in development of models and methods of estimation of reliability and efficiency of generating facilities, creation of digital systems on the basis of continuous accounting and analysis of data on technical condition of power equipment and parameters of electric power generation.
