中文摘要

随着电网对频率支撑、无功补偿及构网能力的需求增加,多台变流器并联运行的协调控制至关重要。本文研究了虚拟同步机(VSM)控制策略,旨在解决多机并联系统在孤岛及并网模式下的稳定性与协调控制问题,为电力电子接口电源提供更强的电网支撑能力。

English Abstract

Transmission system operators (TSOs) are increasingly requesting frequency support, reactive power compensation, and grid-forming capability to power plants interfaced by power converters. In these plants, a large number of converters is operated in parallel and all of them should be adequately coordinated to provide these services. For that purpose, the virtual synchronous machine (VSM) control t...
