摘要:

针对低惯量系统难以应对因高比例新能源接入引发的频率突变问题,提出一种考虑多类储能参与电力系统频率调节的协同控制策略。首先,通过低通滤波处理频率变化率信号,实现电化学与飞轮储能协调控制;再结合多类型储能协调控制模型、新能源出力波动及传统火电机组响应滞后特性,建立系统频率响应(system frequency response,SFR)模型;然后,构建储能系统参与第二道防线频率调整的控制策略模型,并制定差异化充放策略以平衡即时与长期调节需求;最后,在仿真平台进行验证,所提策略可使系统频率暂态恢复速度提升44.3%,有助于提升电力系统频率稳定性。

Abstract:

A synergistic control strategy is proposed considering 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 electrochemical 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 differentiated 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.

Key words: electrochemical energy storage, flywheel energy storage, energy storage coordination control
