| Abstract:Structure design will affect the construction cost and operation performance of hybrid AC/DC micro-grid. This paper takes an overall contrastive analysis on the typical structures of AC micro-grid and DC micro-grid. According to the partition principle, hierarchical principle, maximum resource utilization principle and the principle of electric energy quality assurance in micro-grids, three topological structures for hybrid AC/DC micro-grid are designed, which are multilayer type, single loop type and complementary loop structure. Using analytical method for reliability and economy and reference data in micro-grid, this paper compares the three new topologies on system reliability index and economic index such as construction cost, operation and maintenance cost and so on. Each structure’s characteristics and application are given.
