Abstract

This paper proposes a distributed multi-strategy particle swarm optimization algorithm to improve the solution accuracy of solving the multi-area interconnected economic dispatch problem involving wind power, photovoltaic power generation, and energy storage units. Additionally, the proposed approach enhances the privacy protection capability among areas. Firstly, to improve the global search ability of the particle swarm optimization algorithm, the population is partitioned using a competition mechanism. Then, different strategies are applied according to the partition results to enhance the algorithm diversity. Secondly, a multi-area interconnected economic dispatch model with wind power, photovoltaic power generation and energy storage units is constructed, where information is transmitted between areas through tie-lines, and then a distributed method is proposed to be applied in a multi-strategy particle swarm optimization algorithm, where each sub-algorithm solves the sub-problems related to each area separately. Finally, the IEEE39-bus system is divided into two-area and three-area interconnected systems, and the performance of the algorithm is verified on the modified IEEE 39-bus system, and the experimental results verify the effectiveness of the particle swarm optimization algorithm based on competitive partitioning and the feasibility of the distributed approach by comparing and analyzing the algorithms with the other three optimization algorithms.
