| 摘要: |
| 结构设计关系到交直流混合微电网的建设成本和运行性能。对交流微电网、直流微电网的典型结构进行了比较全面的对比分析。根据微电网的分区原则、分层原则、资源利用最大化原则、电能质量保证原则，设计了交直流混合微电网的3种拓扑结构，分别为多层型、单环型以及互补环型结构。利用微电网可靠性和经济性的分析方法及参考数据，对比了3种拓扑的系统可靠性指标和建设成本、运行维护费用等经济性指标，得出其各自的优缺点和适用场合。 |

| 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.
