Research on Microgrid Division of Solar and Wind Energy Enrichment Expressway Distribution Network Based on IPSO

The distribution form of expressway is narrow and long, the distance between power supply and different loads is uncertain, and there may be multiple long-distance power transmission. The distribution network of expressway is divided into multiple independent microgrids, which can better adapt to the access of a large number of electric vehicles, energy storage equipment and flexible loads to the highway distribution network, and improve the utilization rate of renewable energy in the road area. In this paper, the optimization of the distance between nodes is transformed into the optimization of the cost. With the objective of the optimal network loss, the forward and backward generation method is used to calculate the power flow of the distribution network containing distributed power generation, and the corresponding basic loop matrix is generated through the topology of the distribution network. IPSO is used to solve the distribution network reconfiguration model. The simulation results using IEEE33 node model show that compared with traditional distribution network, the proposed microgrid division method can effectively reduce network loss and provide support for the development of traffic energy integration.
