英文摘要：

Microgrid integrated the advantages of distributed generation, provided an effective method for grid connected power generation of new energy. An elaborate description for the background of microgrid was given. The traditional grid defects and disadvantages of distributed generation were pointed out, and then the concept of microgrid was extended. On this basis, the definition of microgrid, the concept of designing the microgrid and the current development of microgrid around the world were introduced. Then the key technical problems including operation characteristics and control method of the microgrid was analyzed. Finally, the future of microgrid in China was discussed.
