中文摘要

电网故障是电力系统最严重的扰动之一,威胁电网可靠性。为缓解此问题,分布式发电逆变器可通过提供电压支撑来辅助电网。本文研究了在阻感性电网中,如何通过正负序电流控制策略,在满足电流注入限制和电网阻抗约束的前提下,最大化电压支撑能力。

English Abstract

Grid faults are one of the most severe perturbations in power systems. During these extreme disturbances, the reliability of the grid is compromised and the risk of a power outage is increased. To prevent this issue, distributed generation inverters can help the grid by supporting the grid voltages. Voltage support mainly depends on two constraints: the amount of injected current and the grid impe...
