| 摘 要： | 针对AGC控制中火电机组响应时滞长、机组爬坡速率低的问题,提出了一种基于模糊控制策略的电池储能系统(Battery Energy Storage System,BESS)辅助AGC调频方法。该方法以区域控制偏差(Area Control Error,ACE)及其变化率作为模糊控制器的输入量,BESS的参考功率变化量作为输出量,根据系统的运行状态调节BESS输出功率,辅助火电机组改善电网的动态调频性能。基于Matlab/Simulink平台的仿真结果表明,BESS能够迅速响应负荷扰动,减小了系统频率偏差和联络线功率偏差,降低了系统的超调作用,有助于提高电网AGC调频能力和增强系统的稳定性。

| Abstract: | As the thermal power units often require a long time to response to load disturbance and have low unit ramp rate, a method of battery energy storage system assisted automatic generation control based on fuzzy control strategy is proposed. This fuzzy controller uses Area Control Error (ACE) and its rate of change as inputs and the reference power variation as output. BESS output power is adjusted according to the system's operating status, assisting to improve the dynamic performance of the grid frequency regulation. Simulation results based on Matlab/Simulink platform show that BESS responds quickly to load disturbance, thus reducing the system frequency deviation and tie-line power deviation, lowering the unit ramp rate requirements, and improving the stability power system. |
