Abstract

Abstract: Based on the energy storage system involved in the economic evaluation of power frequency modulation (FM),the efficiency comparison between energy storage system and conventional units was made.This paper proposed an economic evaluation model of energy storage systems,optimal allocation of economic optimum capacity,economy evaluation method of energy storage systems in power frequency modulation,the energy storage system equivalent life calculation method based on the rain flow count method as well as the energy storage system with conventional FM power supply efficiency comparison method.From the multiple perspectives,the high efficiency of the energy storage system participating in electric power primary frequency control was verified.

Key words: energy storage system, power system, frequency modulation, evalution, rain flow count method
