Inertia Response Improvement in AC Microgrids: A Fuzzy-Based Virtual Synchronous Generator Control

语言:

中文摘要

由于转换器接口微电网缺乏旋转质量,系统惯量不足,导致频率波动剧烈且频率最低点(nadir)较高,影响系统动态性能及保护装置运行。本文提出一种基于模糊逻辑的虚拟同步发电机(VSG)控制策略,旨在提升微电网的惯量响应能力,改善频率稳定性。

English Abstract

The absence of rotational masses from synchronous generators in converter-interfaced microgrids leads to a lack of inertia. Consequently, the system exhibits steeper frequency variations and higher frequency nadir, which may degrade the dynamic performance and challenge the operation of sensitive equipment such as protective relays in the grid. Virtual synchronous generator is introduced as an eff...

该技术直接契合阳光电源构网型(Grid-Forming, GFM)技术路线。随着高比例可再生能源接入,电网强度减弱,阳光电源的PowerTitan系列储能系统及大型组串式逆变器需具备更强的弱电网支撑能力。通过引入模糊逻辑优化VSG参数,可显著提升设备在孤岛或弱网环境下的频率响应速度与稳定性。建议研发团队将该自适应控制算法集成至iSolarCloud平台及PCS控制固件中,以增强产品在复杂电网环境下的黑启动及惯量支撑性能,提升产品在电力辅助服务市场中的竞争力。
