Abstract

The relevance The installed capacity of renewable energy sources increases annually relative to the total installed capacity. Features of work inherent in renewable energy installations modify the nature of transient processes in electric power systems during emergency modes. A number of authors, when studying the operation of renewable sources as part of the energy system, consider the parallel operation of renewable sources with a powerful electric power system, and also do not take into account the drive motors of power plant generators. In this paper, the study of transient processes is carried out in an isolated electric power system with renewable energy sources, the power of which is comparable to the power of classical generators. This work is dedicated to the study of transient processes in an isolated electric power system with renewable energy sources, the power of which is comparable to the power of classical generators. The research takes into account the model of a synchronous generator drive motor and its control system, configured in accordance with applicable requirements and standards. Aim of research The main aim of the research is to assess the impact of renewable energy sources on the operating modes of an isolated gas turbine power plant during emergency disturbances. Research methods To achieve the main aim of the research the method of the simulation mathematical modeling in Matlab/Simulink was used. Results During the research, a number of curves were obtained that characterize the operating modes of an isolated power system during an emergency process. The analysis of these curves has showed that the stable operation of the power plant is possible with the installed capacity of renewable energy sources not exceeding 60 % of the power reserve of the power plant's lead generator.
