Abstract

Abstract: Aiming at the impact of new energy consumption on distribution operation, a distribution network topology reconfiguration method considering both new energy consumption and voltage deviation is proposed to realize the balance and coordination between the two. Firstly, a scenario reduction technique based on scenario similarity is used to obtain representative new energy power samples. Then, a multi-objective stochastic optimization reconfiguration mathematical model is established to optimize the amount of new energy consumption and the voltage deviation at distribution network nodes. Subsequently, a multi-objective particle swarm algorithm guided by a proximal strategy optimization algorithm is employed to efficiently search for the corresponding Pareto solution set. Finally, the technique for order of preference by similarity to ideal solution decision method is applied to balance the trade-off between wind power consumption and voltage deviation and select the final reconfiguration scheme. The improved IEEE-33 node distribution network is used as the test object, and the experimental results verify the effectiveness of the proposed method.
