Abstract

A power flow optimization strategy of the active distribution network including three-terminal SOP with energy storage system is proposed in this paper. A multi-objective optimization mathematical model, whose decision variables are the SOP active power and reactive power, is built. Under various constraints, the minimum active power loss and minimum voltage deviation are obtained in the distribution network. The multi-objective particle swarm optimization algorithm is used to obtain the global optimal solution. The SOP optimal installation location is selected. The active distribution network active power loss is reduced, and the voltage level is improved. Finally, the optimization effects on the improved IEEE 33-node system from different types of SOP are compared and analyzed in detail. The effectiveness of the proposed optimization strategy is verified in the aspects of the distribution network power flow optimization and economic benefit improvement.
