摘　　要：新型电力系统中新能源渗透率不断增加,输电网和配电网协同运行环境复杂多变,对输配协同优化算法的收敛性提出了更高的挑战。鉴于此,应用广义主从分裂法将输配协同无功优化问题分解为输电网和多个配电网的并行优化问题;为改善广义主从分裂法的计算效率,提出了基于功率、电压等多元信息交互及历史信息修正的双向安德森加速策略;在此基础上,提出了融合原对偶内点法、启发式算法和辅助函数的输配协同无功优化方法,实现了输电网和配电网多种类灵活性资源的协调配合和优化控制。算例仿真结果表明,所提方法能有效改善主从分裂法边界的收敛性能,在大规模分布式能源接入的输配协同无功优化场景中具有更好的应用价值。The increasing penetration rate of renewable energy in new power systems has led to a complex and ever-changing coordinated operation environment for transmission and distribution networks,posing higher challenges to the convergence of transmission and distribution coordinated optimization algorithms.In view of this,based on the generalized master-slave splitting method(GMSSM),the transmission and distribution coordinated reactive power optimization problem is decomposed into parallel optimization problems of the transmission network and multiple distribution networks.To improve the computational efficiency of the GMSSM,a bidirectional Anderson acceleration strategy is proposed based on the interaction of multiple information such as power and voltage,as well as historical information correction.On this basis,a transmission and distribution coordinated reactive power optimization method combining primal dual interior point method,heuristic algorithm,and auxiliary function is proposed to achieve the coordinated coordination and optimization control of multiple types of flexible resources in the transmission and distribution networks.The simulation results of the case show that the proposed method can effectively improve the convergence performance of the master-slave splitting method boundary,and has better application value in the scenarios of transmission and distribution coordinated reactive power optimization with large-scale distributed generators.
