基于虚拟同步发电机的光-储调频控制策略研究
Strategic Studies on Frequency-modulated Controlling of Photovoltaic-Energy Storage System Based on Virtual Synchronous Generator
摘要
Abstract
As a kind of renewable-energy-based power generation,photovoltaic power generation has been increasingly used for power system.And meanwhile,more attention is paying to the effect of system stability.The paper began with analysis of the output characteristics of photovoltaic system.In view of the absence of inertia of grid-connected photovoltaic power generation in the event of frequency fluctuation,the ideas to make up for the system virtual inertia with the stored energy were presented in the paper.By using the controlling strategies for virtual synchronous generator to the energy storage inverter,the integrated photovoltaic-storage system would work as a whole the same way with the synchronous generator.And meanwhile,it would maintain the stable output PV power of the integrated photovoltaic-storage system.At last,PSCAD/EMTDC simulation was used to verify the effectiveness of making up for the virtual inertia through the controlling strategies presented in the paper.关键词
