摘要(Abstract):
提出一种基于带精英策略的快速非支配排序遗传算法(non-dominated sorting genetic algorithm-II,NSGA-II)和逼近理想解排序(technique for order preference by similarity to ideal solution,TOPSIS)的含VSC-HVDC交直流系统多目标最优潮流算法,统一协调系统运行的经济性及环保要求等目标。首先,基于含VSC-HVDC交直流系统的稳态模型,建立了综合考虑网络损耗和环境因素的多目标最优潮流模型;然后,采用混合编码方式,通过NSGA-II得到帕累托最优解集;最后,采用TOPSIS法评估各决策方案的相对优劣,以帮助运行人员选取有效的折中解。基于IEEE 14节点系统和IEEE 118节点系统的算例结果验证了所提方法的有效性。
