摘要(Abstract):
为了抑制光伏发电的随机性和波动性的影响，提高微电网的供电可靠性，对离网工况下的微电网黑启动方案进行分析，并将其与虚拟同步发电机（Virtual Synchronous Generator,VSG）控制策略一起应用于储能变流器中，建立了储能变流器的VSG数学模型，推导了小信号模型表达式，通过在光储微电网系统引入惯性和阻尼，提高了系统电压和频率的稳定性。最后，在Matlab/Simulink仿真平台上搭建模型，验证了零起升压策略的有效性，确保了黑启动过程中线路电压的稳定；并在并网工况下分析了光储微电网系统各个微源之间的协调控制，验证了构网型光储变流器控制策略的有效性。
