Large-scale energy storage battery technology participates in the application of AGC frequency modulation in thermal power plants

With the increasingly strict AGC assessment, energy storage system to participate in AGC frequency modulation technology to meet the development opportunities. This paper introduces the application status, basic principle and application effect of the largest side energy storage system in China, analyzes the comprehensive frequency modulation performance index and economic benefits before and after the energy storage system is put in, and the inspiration of energy storage system combined with thermal power plant frequency modulation to the power grid.
