An Overview on Analysis and Control of Micro-grid System

Micro-grid control is the key technology in the process of accessing micro-grid into regular grid. This paper summarizes several ways on coordination control in micro-grid and introduces some domestic researches on micro-grid control strategies. It is written on the basis of the achievements on micro-grid control in some developed countries and current situations on domestic micro-grid control. Firstly, the paper introduces the objects of micro-grid control study and describes the control processes of each object thoroughly on different micro-grid control structures. Then the paper states the researches among the world on micro-grid control generally. In the end, the paper discusses the research orientation on micro-grid control which based on the existing problems of micro-grid control and current situations on regular grid.
