Abstract
With the development of distributed generation technologies, AC/DC hybrid microgrid is getting more and more extensive research and applications, where the interlinking converter (IC) is one of the key components. This paper proposes a novel interlinking converter control method based on current-controlled virtual synchronous generator (VSG). By employing the proposed method, the microgrid can not only properly share the loads between the AC and DC sub-grids under the steady state, but also smooth the response of the whole system during the significant load disturbance and reduce the coupling influence of fast power fluctuation of AC/DC sub-network. Matlab/Simulink simulations verify that the proposed method can lower power conduction infiuence of AC/DC sub-network and help to improve the operation stability of AC/DC microgrid.关键词
