摘要
Abstract
Considering the deviating regulation characteristics of AC frequency and DC bus voltage of the existing AC/DC hybrid micro-grids,virtual synchronous generator(VSG)is applied to an interlinking converter(ILC)connected to the AC and DC micro-grids. The transmission power of ILC is obtained by sending the DC micro-grid bus voltage devia?tion and AC micro-grid frequency deviation to their own PI controllers,respectively. Using this technology,the hybrid micro-grid can not only respond smoothly during load switching,but also always keep the AC frequency and DC bus voltage of the hybrid micro-grid operating at rated values. In addition,simulations are conducted using simulation soft?ware PSCAD,which verify that the proposed theory agrees well with simulation results.关键词
