【 摘 要 】

AC/DC hybrid micro-grid combines the advantages of DC and AC micro-grids, and it is one of the future development directions for micro-grid. Five kinds of typical structures of AC/DC hybrid grid are introduced, and the functions and characteristics of those structures are analyzed. Considering the influence of micro-grid structure on the power supply reliability, three kinds of AC/DC hybrid power grid reliability evaluation methods are established, which are the Minimal Path Method, the Convolution Method and the Monte-Carlo Simulation Method. The reliability of five typical structures is analyzed and compared by using three kinds of reliability evaluation methods.
