摘要
为减小独立微电网系统输出无功均衡的误差,通过搭建微电网系统模型,提出将下垂控制和虚拟阻抗相结合的改进策略,并通过Matlab进行仿真验证.结果表明:在改进下垂控制后,微电网系统的均流效果明显改善,有功和无功功率的均衡性能有所提高.
In order to reduce the error of the system output reactive power balance,by building a microgrid system model,an improved strategy combining droop control and virtual impedance is proposed,which is simulated and verified by Matlab.The results show that the current sharing effect of the microgrid system is significantly improved,and the balanced performance of active and reactive power is improved under the improved droop control.
