基于一致性的并联虚拟同步发电机分布式协同控制
Consensus-based distributed control for parallel-connected virtual synchronous generator
摘要
Abstract
Virtual synchronous generator (VSG) can mimic the operating mechanism of the synchronous generator, which can provide inertia and damping support for system. In islanded mode, parallel-connected VSGs mainly use de-centralized droop control and the system is not able to restore frequency or reasonably share active power. To solve these problems, a distributed control strategy of parallel-connected VSGs based on consensus algorithm is proposed. The control strategy can improve the frequency and active power characteristics of the system. The mathematic model of traditional VSG control is firstly demonstrated. Based on that, the whole control scheme of frequency restoration and active power sharing for parallel-connected VSGs is established. With distributed control strategy, the scheme utilizes distributed com-munication network exchanging few information between neighbor VSGs to make the system restore frequency to nominal value and reasonably share active power to satisfy different demand. Simulation results verify the validity and effectiveness of the proposed control strategy.关键词
