摘要
在直流微电网设计中,下垂控制是应用较广泛的DC/DC均流控制方式,但是传统的下垂控制方法中母线压降和均流效果是相互制约的,无法两者兼顾。为了解决此问题,本文提出一种新的下垂控制方式,根据系统状态不同自动调节输出点,在一定程度上兼顾均流效果和母线压降。
In the design of DC microgrid,droop control is a widely used DC/DC current sharing control method,but the bus voltage drop and current sharing effect of traditional droop control method are mutually restrictive and cannot take into account both.To solve this problem,a new droop control method was proposed in this paper.The output points were automatically adjusted according to different system states,which taken into account the current sharing effect and bus voltage drop to a certain extent.
