针对电氢耦合储能直流微网中母线电压易波动和储氢状态(state of hydrogen,SOH)易越限的问题,提出了一种考虑SOH和直流母线电压稳定性的电氢耦合储能直流微网协调控制策略。首先,氢储能系统(hydrogen energy storage system,HESS)采用基于模糊算法的下垂控制策略,综合考虑母线电压波动和SOH对HESS的输出功率进行动态优化。其次,电池储能系统(battery energy storage system,BESS)采用基于类似虚拟同步发电机(analogous virtual synchronous generator,AVSG)的控制策略模拟电容的充放电特性,对直流母线电压的动态性能进行优化。最后,考虑母线电压波动幅值,通过控制HESS和BESS的运行模式对母线电压进一步协调优化。在Matlab/Simulink平台中搭建了电氢耦合储能微网仿真模型,验证所提策略的有效性。结果表明:所提协调控制策略能够在源荷波动场景下提升直流微网母线电压的稳定性、改善氢储能系统的过充过放情况。
