Power Flow Optimization Method Research for the AC/DC Distribution Network with Energy Routers

AC/DC hybrid distribution network is the future development trend of power grid, and the energy router in the distribution network can play a role of power flow control, to achieve the power management. In order to give full play to the regulation and optimization of energy routers, the optimization of AC/DC hybrid distribution network should be studied, which can improve system performance comprehensively. In this paper, an optimal power flow model for the power system with energy routers is established. Setting network loss and voltage deviation as targets, and using PSO algorithm to build a optimization model, the optional solution set is obtained. Based on the the simulation and analysis of the adjusted IEEE-69 node testing system, the effectiveness of the building model is verified, meanwhile the steady-state model and power flow optimization method for AC/DC distribution network are deeply studied. This paper provides feasible solutions for improving the economy and security for the future distribution network.
