摘　　要：综合考虑区域电网的负荷需求和电池储能系统的荷电状态(SOC)两者之间的关系,提出了一种基于多变量模糊控制的电池储能系统辅助火电机组参与调频的控制策略。以储能装置为研究对象,设计相应的多变量模糊控制器,通过多变量模糊控制方法控制电池储能系统的输出功率,改善系统调频的动态性能。建立了含电池储能系统的区域电网仿真模型,并基于MATLAB/Simulink平台对所提控制策略进行仿真验证。仿真结果表明,控制策略在改善火电机组的调频效果和提高储能装置的使用寿命方面更具有优势。Under overall consideration of the relationship between the load demand of the regional power grid and the state of charge(SOC)of the battery energy storage system,a control strategy based on multivariable fussy control was proposed for the participation of the auxiliary thermal power plant of the battery energy storage system in frequency modulation.Taking energy storage device as the research object,a corresponding multivariable fuzzy controller was designed to control the output power of the battery energy storage system in the multivariable fuzzy control method and improve the dynamic performance of system frequency modulation.A simulation model was set up for the regional power grid with the battery energy storage system,and the proposed control strategy was simulated and validated based on the MATLAB/Simulink platform.Simulation results showed that the proposed control strategy had advantages in the improvement of frequency modulation effect of the thermal power plant and the elongation of service life of the energy storage device.
