Abstract: We developed and verified a mathematical model for the processes of frequency and power control in integrated power systems (IPSs) with wind power plants (WPPs) and accumulator batteries (ABs), which provides an opportunity to analyze the regimes of energy system regulation and formation of the most efficient control laws. It was established that the introduction of high-power WPPs into the structure of generating powers of IPSs can lead to unacceptable frequency deviations in the system.
It was proved that the stabilization of frequency and power in IPSs with powerful WPPs in their composition can be ensured by introducing ABs with a capacity comparable to the installed capacity of WPPs into the IPSs structure. The results of simulation of the modes of these power systems showed that the accuracy of frequency and power regulation in them can be achieved by an accuracy that is higher than normative accuracy for the ENTSO-E power system of the European Union.
Keywords: mathematical model, integrated power system, wind power plant, accumulator battery, regulation, accuracy.
