一种用于含可再生能源和储能的孤岛微电网的无通信分布式控制架构

A Communication-Less Distributed Control Architecture for Islanded Microgrids With Renewable Generation and Storage

语言:

中文摘要

为确保孤岛微电网的可靠运行,需至少一个分布式资源承担构网责任。储能系统通常因其功率补偿能力承担此职责,但在储能达到荷电状态极限时会丧失该能力。本文提出了一种无通信分布式控制架构,通过协调多个分布式资源,在储能受限时维持系统稳定,提升了微电网的鲁棒性。

English Abstract

For reliable operation of an islanded microgrid, at least one of its distributed resources should assume the responsibility of forming the off-grid power system. This responsibility is usually assumed by energy storage systems based on their capability of compensating the unbalance between generation and consumption. However, the storage units lose this capability when they reach the maximum and m...

该研究提出的无通信分布式控制架构与阳光电源的PowerTitan及PowerStack系列储能系统高度契合。在多机并联或微电网应用场景下,该技术可增强系统在极端工况下的构网(Grid-forming)能力,解决单一储能容量受限时的系统稳定性问题。建议研发团队将其引入iSolarCloud智能运维平台及PCS控制算法中,以提升阳光电源在离网及微电网解决方案中的竞争优势,特别是在无通信链路或通信受阻的复杂工商业微电网项目中,该算法能显著提升系统的可靠性与黑启动性能。
