在资源条件固定的情况下,为进一步提高新型多区域电力系统的灵活调度能力,提出一种基于联合备用容量的新型多区域电力系统经济调度模型。首先,通过综合考虑多区域新能源消纳,提出多区域联合备用容量计算理论。其次,基于多区域联合备用容量,构建针对高比例新能源引入的多区域互联电力系统经济调度模型,并使用基于排序分组的自适应多策略差分进化算法求解该调度模型,同时针对模型中的约束条件,提出一种修补策略与罚函数方法相结合的约束处理方法。最后,将所提出方法与传统个体备用容量分别在三区域和四区域电力系统中进行比较,证明基于联合备用容量的新型多区域电力系统经济调度模型的有效性。
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.
