摘　　要：随着高压/特高压直流输电逐渐成为区域电网互联的主要方式,交直流混合电网的高维多目标优化问题已成为需要关注和解决的重要问题。基于此,建立了含HVDC的交直流混合电力系统的四目标最优潮流模型,以发电机成本,电压偏移,电压稳定度和有功网损作为目标,引入更适合处理高维多目标优化问题的NSGA-Ⅲ算法来求取其交直流混合系统的Pareto最优解集。并通过逼近理想解的排序方法确定最终方案供决策者参考。使用30节点交直流混合系统验证模型和算法的有效性。With the high-voltage/ultra-high voltage direct current transmission(HVDC/UHVDC)becoming the main way of regional power grid interconnection,the many-objective optimization problem of AC/DC hybrid power grid has become an important subject which needs to be concerned.Based on this,a four-objective optimal power flow model for AC/DC hybrid power system is established in this paper,which takes the generator cost,voltage deviation,voltage stability and active power loss as the targets.Meanwhile,NSGA-III algorithm is applied to obtain the Pareto optimal solution set and the final scheme is determined to provide a reference for the decision maker by the method of technique for order preference by similarity to ideal solution(TOPSIS).The effectiveness of the proposed model and algorithm is verified by a 30-node AC/DC hybrid system.
