Application of energy storage technology in frequency control of high proportion new energy power system

The frequency quality of power system is an important index of the power grid quality. It is necessary to pay attention to the problem of frequency regulation. As more and more intermittent energy sources are integrated into the grid network, it brings new problem to the power grid. Energy storage technology provides a new available means to alleviate the pressure. This paper presents a scheme of frequency regulation based on energy storage system for frequency regulation of high proportion new energy power system, and studies the mathematical model of the traditional frequency modulation and energy storage system. Also introduces their operation principles and technical characteristics. This paper formulates a responsibility allocation scheme for frequency regulation based on load cycle. The MATLAB/Simulink software is used to build the simulation model of two regional power system frequency regulation based on energy storage system, and the effectiveness of the scheme is verified. In addition, it carries out economic calculation to prove the economic feasibility of the scheme.
