摘要：
Based on the concept of micro-grid, this paper analyzes the advantages of micro-grid relative to large power grid and the existence of power quality problems, which makes the development of micro-grid currently limited. Then, starting from the power supply of the micro-grid, the benefits of distributed energy as a micro-grid energy are expounded.For the three types of micro-grid - DC micro-grid, AC micro-grid, AC-DC micro-grid, a brief introduction is demonstrated, and a profounder analysis is made for the DC micro-grid. In order to solve the power quality problem existing in the micro-grid, the model of the whole micro-grid system is constructed by local modeling of each component in the micro-grid. Finally,this paper introduces a kind of operation mode of micro-grid--connected operation. The problems that the micro-grid can access to the grid and the development prospects of the micro-grid are analyzed.
