摘　　要：随着新能源技术的发展,越来越多的分布式电源接入配电网,增强了输配电网的耦合性,也加大了电力系统电压越限风险。为了解决该问题,提出一种输配电网协调无功优化控制方法。首先,利用主从分裂法完成输配网解耦计算;其次,利用二阶锥规划法求解配电网无功优化子问题,利用改进的遗传算法求解输电网无功优化子问题;最后通过IEEE14节点系统和IEEE33节点系统构成的算例进行仿真,验证了该方法的有效性。With the development of new energy,more and more distributed power sources are connected to the distribution network,which enhances the coupling of the transmission and distribution network and increases the risk of voltage out of limit in the power system.To solve this problem,a coordinated reactive power optimization control method for transmission and distribution network is proposed in this paper.Firstly,the master-slave splitting method is used to complete the decoupling calculation of transmission and distribution network;Secondly,the second-order cone programming method is used to solve the reactive power optimization subproblem of distribution network;The improved genetic algorithm is used to solve the reactive power optimization subproblem;Finally,the effectiveness of the proposed model and algorithm is verified by simulation of IEEE14 buses system and IEEE33 buses system.
