Stability Control and Inertia Matching Method of Multi-Parallel Virtual Synchronous Generators
摘要
Abstract
Virtual synchronous generator technology has attracted more and more attention. As a new control method, it can allow the distributed generation actively taking part in the frequency and voltage regulation of the grid. By mimicking the characteristics of the synchronous generator, the micro power source inverters have the same characteristics of the synchronous generator, such as the inertia, primary frequency modulation, reactive power and voltage modulation etc. Simple VSG virtual inertia controller is proposed to avoid the impacts of frequency command fluctuation on the stability of the system caused by the phase-locked loop (PLL) error. The small signal model of parallel VSGs including the state variables of intermediate control link is established. And then the influences of the main control parameters on system stability and dynamic response are analyzed. At last, based on the principle of equivalent synchronous generator, virtual inertia matching method of the parallel virtual synchronous generators is proposed. Simulation and experimental results verify the proposed method.关键词
