基于自适应调节的微源逆变器虚拟同步发电机控制策略
Control Strategy of Virtual Synchronous Generator Based on Adaptive Adjusting for Distributed Inverters
摘要
Abstract
Micro-grid enables distributed power realize distributed development, local absorb and efficient application, but its inertia in islanding is small, and the frequency is greatly affected by load fluctuations. The introduction of virtual synchronous generator control strategy to improve micro-grid system frequency stability plays an important role, and the inertia parameters of virtual synchronous generator control strategy is introduced virtually, it can refer to the actual parameters of synchronous generator and can adjust flexibly according to needs. An adaptive adjustment of virtual synchronous generator control strategy is proposed, which can correct virtual inertia parameters according to the actual operating conditions in real-time and ensure the safety and stable operation of micro-grid systems. Both the correctness and validity of the proposed control strategy have been verified by the simulation results in Matlab/Simulink platform.关键词
