多类型储能参与电力系统频率调节的协同控制策略
Coordinated control strategy for multi-type energy storage participating in power system frequency regulation
摘要
Abstract
A synergistic control strategy is proposed consi-dering the participation of multiple types of energy storage in the power system frequency regulation to address the issue of low-inertia system's difficulty in coping with the frequency fluctuations caused by the high proportion of new energy access.Firstly,the frequency change rate signal is processed by a low-pass filter to realize the coordinated control of electro-chemical and flywheel energy storage.Then,combined with the coordinated control model of multi-type energy storage,the fluctuation of new energy output and the lagging response characteristics of traditional thermal power units,the system frequency response(SFR)model is established.Next,a control strategy model for energy storage system participating in the secondary frequency adjustment is constructed,and differen-tiated charging and discharging strategies are formulated to balance the immediate and long-term regulation needs.Finally,verification is conducted on the simulation platform,and the proposed strategy can improve the transient recovery speed of the system frequency by 44.3%,which helps to enhance the frequency stability of the power system.关键词
