摘要

分布式发电机组通过接口逆变器连接到微电网。接口逆变器对微电网的运行性能起着至关重要的作用。本文研究了微电网孤岛运行时，采用P-F/Q-V下垂控制的接口并联逆变器控制问题。在孤岛模式下，逆变器下垂控制应保持电压和频率的稳定。实现了并联逆变器的下垂控制，实现了各逆变器负载的比例分担。在Matlab/Simulink中对逆变器的下垂控制进行了仿真，结果表明下垂控制对平衡电压幅值、频率和功率共享有显著的效果。

Frequency and voltage droop control of parallel inverters in microgrid

The distributed generation units are connected to microgrid through an interfacing inverter. Interfaced inverter plays main role in the operating performance of microgrid. In this paper, interfaced parallel inverter control using an P-F/Q-V droop control was investigated, when microgrid operated in islanded mode. In islanding mode the inverter droop control should maintain voltage and frequency stability. The droop control for parallel inverters is implemented and the proportional load sharing is obtained from each individual inverter. Droop control of inverter is simulated on Matlab/Simulink, the results indicate droop control has a significant effect on balancing the voltage magnitude, frequency and power sharing.
