摘要

本文提出了一种并网隔离模式下直流微电网的分布式无下垂电压控制方法。所提出的控制技术基于分布式共识方法,解决了集中式控制器容易出现单点故障的可靠性问题,同时比传统的分散下垂控制器更有效地在分布式能源(DERs)之间共享负载。在厦门大学的实际直流微电网模型中,基于各种现实场景,采用时域仿真对分布式控制方案进行了实现、演示,并与传统的下垂控制进行了比较。

Distributed Voltage Control of DC Microgrids
This paper presents a distributed, droop-free voltage control of a dc microgrid in grid-connected and isolated mode. The proposed control technique, based on a distributed consensus approach, addresses reliability issues of centralized controllers that are prone to single point failure, while sharing the loads among Distributed Energy Resources (DERs) more effectively than conventional decentralized droop controllers. The distributed control scheme is implemented, demonstrated, and compared with conventional droop control using time-domain simulations for a model of an actual dc microgrid in Xiamen University, China, based on various realistic scenarios.
