摘要

针对配电网中存在的柔性负荷利用不充分、不灵活,需求参与响应滞后,新能源输出不确定等一系列问题,提出了一种基于目标的差异化配电网优化运行方法。首先,对灵活负荷进行分类,并建立相应的数学模型。其次,考虑到新能源输出的不确定性,采用机会约束程序设计,建立多目标优化模型,以降低配电网经济成本、减少网络损耗、提高供电可靠性。随后,引入了一种改进的 NSGA-III 算法来处理多目标模型。最后,以一个 11 节点的配电网络为例,对三种不同的算法进行了综合比较。这证实了本文提出的优化调度方案的合理性。

Multi-objective optimization scheduling method considering flexible load integration for distribution network
In response to a series of issues in the distribution network, such as inadequate and inflexible utilization of flexible loads, delayed response to demand participation, and the uncertainty of new energy source output, a differentiated objective-based method for optimizing distribution network operations is proposed. Firstly, flexible loads are categorized, and corresponding mathematical models are established. Secondly, by employing chance-constrained programming to account for the uncertainty in new energy source output, a multi-objective optimization model is developed to reduce distribution network economic costs, decrease network losses, and enhance power supply reliability. Subsequently, an improved NSGA-III algorithm is introduced to address the multi-objective model. Finally, an 11-node distribution network is used as a case study, and three different algorithms are comprehensively compared. This confirms the rationality of the optimized scheduling scheme proposed in this paper.
