摘要：

With the development of new energy and for improving the utilization of hybrid AC/DC micro-grid renewable energy, this paper proposes a structure and control method of hybrid AC/DC micro-grid, and studies on its stability. In order to solve the problems of voltage fluctuation, power balance etc. the DC side output photovoltaic power into the grid at a constant through the AC side, in order to improve the DC side photovoltaic utilization; in stand-alone operation mode, the battery, as the balance nodes, maintain the stability of the whole system and achieve power exchange between AC micro-grid system and DC micro-grid system with the bi-directional AC/DC converter. The simulation of the system is carried out by using PSCAD/EMTDC software, and analyzing the small-signal stability.
