摘　　要：交直流混合配电网是未来电网发展的趋势,而能量路由器在配电网中能够发挥关键的潮流管控的作用,实现对电能的调控,改善电能质量。目前已有较多针对能量路由器的结构以及控制策略方面的研究,但对于含能量路由器的交直流混合配电网的潮流分布以及潮流优化的研究较少。为了更好地发挥能量路由器的整体调控和运行优化的作用,研究含能量路由器的交直流混合配电网多目标最优潮流问题很有必要。对此,建立含能量路由器的交直流混合系统多目标最优潮流模型,以网络损耗和电压偏差为目标,利用多目标进化算法构建多目标优化模型,求解Pareto解集;随后,采用模糊隶属度法对Pareto解集进行折中决策得到最优折中解。通过对IEEE-69节点测试系统的仿真与分析,验证所构建模型的有效性,并将最优折中解方案与PSO算法求解同系统的SOPF问题方案相对比,证明建立的优化模型相比于单目标优化更能提高系统综合性能,优化系统整体运行状态。AC/DC hybrid grid is the trend of future power grid development,and energy router can play the key role of power flow control in the distribution network,realize the regulation of electric energy and improve power quality.At present,there have been many studies on the structure and control strategy of energy routers,but there are few studies on the power flow distribution and power flow optimization of AC/DC hybrid distribution networks with energy routers.In order to better play the role of energy router regulation and system operation optimization,it is necessary to study the multi-objective optimal power flow problem of AC/DC hybrid distribution network with energy router.Therefore,a multi-objective optimal power flow model of AC/DC hybrid system with energy routers is established.Taking network loss and voltage deviation as objectives,a multi-objective evolutionary algorithm is used to construct a multi-objective optimization model and solve the Pareto solution set.Then,the fuzzy membership method is used to make compromise decision on the Pareto solution set to obtain the optimal compromise solution.Through the simulation and analysis of the IEEE-69 nodes test system,the effectiveness of the constructed model is verified,and the optimal compromise solution is compared with the PSO algorithm to solve the SOPF problem of the same system.It is proved that the optimization model established can improve the overall performance of the system and optimize the operation state of the system.
