Research on distribution network reconfiguration based on microgrid

Micro-grids have been considered as a vital part of power system. The distribution system is gradually showing the characteristics of multi-source initiative. The distribution network reconfiguration with microgrid changes the topology of the network by controlling the state of the switch, and optimizes the predetermined indicators under the premise of safe, economic and stable operation. This paper describes a hierarchical distribution network reconfiguration strategy with microgrid, which can reduce the number of operation of the switch and the network loss. This strategy ensures rapid power supply recovery. In the process of reconstruction, this paper uses the immune clonal selection differential evolution algorithm. The simulation examples are included to display the performance of the proposed method.
