Abstract

To further improve the flexible scheduling capability of the new multi-area power system under unchanged resource conditions, a novel multi-area power system economic dispatch model based on joint reserve capacity is proposed. Firstly, by comprehensively considering the multi-area renewable energy consumption, the multi-area joint reserve capacity calculation theory is proposed. Second, based on the multi-area joint reserve capacity, a multi-area interconnected power system economic dispatch model is constructed for the introduction of a high proportion of renewable energy, and the dispatch model is solved using sorted grouping-based adaptive multi-strategy differential evolution algorithm. Meanwhile, for the constraints in the model, a constraint handling method combining the repair strategy and the penalty function method is proposed. Finally, the proposed method is compared with the traditional method in three-area and four-area power systems, respectively, to verify the effectiveness of the new multi-area power system economic dispatch model based on joint reserve capacity.
