A Frequency Regulation Method of Energy Storage System Based on Adaptive Adjustment of Virtual Synchronous Generator Control Parameters
摘要
Abstract
[Objectives]The large-scale penetration of wind power has reduced the frequency regulation capability of the power system to a certain extent.As a relatively mature and effective technical means,the energy storage system is widely used in power grid frequency regulation.Therefore,the response process and optimal configuration of energy storage system(ESS)participating in power grid frequency regulation under the control of virtual synchronous generator were studied.[Methods]Based on the simulation software DIgSILENT/PowerFactory,an ESS control model and typical power system were constructed to analyze the frequency response characteristics of the grid before and after the ESS participation.Furthermore,considering the reserve capacity of wind turbines under different output modes,the configuration results of the ESS were optimized by dividing the wind speed range and determining the wind turbine power reserve coefficient,so as to realize the adaptive adjustment of the frequency regulation coefficient of the ESS.[Results]The investment of the ESS can effectively improve the frequency response and reduce wind curtailment of the system.By reserving the frequency regulation capacity of wind turbines reasonably,the ESS can provide reliable power support for the power grid.[Conclusions]The self-adaptive adjustment method of the frequency regulation coefficient of the ESS based on the wind speed and the output power of fans can effectively reduce the overshoot and the output power of the ESS while meeting the frequency regulation requirements,thereby extending the working time.关键词
