中文摘要

本文提出了一种针对储能系统的协调电压-频率支撑策略,该策略充分考虑了电网阻抗的电抗-电阻比(X/R比)。与传统方法不同,该方案通过优化功率电子变换器的控制逻辑,提升了储能系统在异常电网条件下的系统稳定性,增强了分布式储能接入配电网后的电压与频率调节能力。

English Abstract

Power electronics converters are utilized for interconnecting distributed energy storage systems into the grid. These converters can support the stability of the power system under abnormal grid conditions. In this article, a new coordinated voltage-frequency support strategy is proposed for energy storage systems considering the reactance-to-resistance ratio of the grid impedance. Unlike conventi...

该研究直接契合阳光电源PowerTitan和PowerStack等储能系统产品的核心控制需求。随着电网环境日益复杂,尤其是弱电网场景下,传统的跟网型控制已难以满足稳定性要求。该协调控制策略可优化PCS(储能变流器)的响应逻辑,提升阳光电源储能系统在电网波动时的电压支撑与频率调节性能。建议研发团队将此策略集成至iSolarCloud智能运维平台及PCS底层控制固件中,以增强产品在微电网及复杂配电网场景下的构网型(GFM)运行能力,提升市场竞争力。
