摘要
以电阻式低压微电网为研究对象,采用虚拟阻抗改进下垂控制,在电源突变后,使逆变器的有功变化和无功变化的最大值减小,改善了系统稳定性。
Taking resistive low-voltage microgrid as an example,the improved droop control based on virtual impedance is applied to decrease the maximum value of both active and reactive changes of the inverter as power supply suddenly varies.So the stability of the system is improved.
