Multi-Objective Optimal Power Flow for DC Distribution system

摘要：

　　The goal of maintaining system operation stability, improving reliability and reducing loss in DC distribution system can be achieved through optimal power flow (OPF). Firstly, a multi-objective OPF model of DC distribution system targeting on reducing system total fault rate and power loss is established with consideration of constrains including converter capacity, operation safety and the charge-discharge rate of energy storage devices. The multi-objective optimization of power flow is converted into single objective optimization using the lexicographically stratified method, then its solved effectively by second-order cone programming. Finally, through multi-period simulation of a 5 node system, the efficiency and accuracy features of the proposed method is verified, and the algorithm achieves optimization of both reliability and economic efficiency.
