Research on Topology of DC Distribution Network Based on Power Flow Optimization

As an important means to achieve energy internet, DC distribution network has great research significance. This paper focuses on the topology of DC distribution network. Considering the power quality and economy, a mathematical model of power flow optimization is proposed and solved in Matlab. The analysis of the results shows that the method is reasonable and effective. Based on the optimization results, voltage deviation and power loss are compared in different topologies, and the operation costs are also calculated. Taking the construction cost into account, the circle topology should be selected. The conclusion provides a reference for DC distribution network planning.
