Research of Distributed Power Grid Method and Control Strategy

Combining with the development of distributed power supply, this paper introduces the grid-connection control strategy of the key device in AC micro-grid and the typical distributed power in DC micro-grid, and puts forward a feasible AC and DC hybrid micro network structure. It analyzes the advantages and disadvantages of different micro networks in their implementation process on the bases of the present network technology, and suggests the way of distributed power connected to the grid
