针对高比例光伏接入下有源配电网产生的较高网损的问题，提出了利用旋转式潮流控制器(RPFC)与无功补偿电容器组(CB)的协调优化降损方法。首先，建立智能软开关(SOP)及RPFC这两种柔性互联装置模型；其次，以配电网总运行费用最低为目标，建立含SOP/RPFC和无功补偿装置(CB)的有源配电网二阶锥优化模型；最后，在改进的IEEE33节点配电网下分别对不同配置方案的配电网二阶锥模型进行仿真求解。结果表明，通过RPFC与无功补偿装置CB的协调优化，在经济性与降损效果方面均优于SOP与CB的组合，同时电压也运行在安全范围，可实现配电网的安全经济运行。
Abstract：To solve the problem of high network loss in active distribution networks with high penetration of photovoltaic integration, a coordinated optimization method for loss reduction using rotary power flow controller(RPFC) and capacitor bank(CB) for reactive power compensation is proposed. Firstly, models of two flexible interconnection devices, soft open point(SOP) and rotary power flow controller(RPFC) are established; secondly, a second-order cone optimization model for the active distribution network incorporating soft open point(SOP), rotary power flow controller(RPFC) and reactive power compensation devices(CB) is developed, with the objective of minimizing the total operating cost; finally, the second-order cone model of the distribution network with different configuration schemes is simulated and solved under the improved IEEE33 node distribution network. The results show that through the coordinated optimization of RPFC and the reactive power compensation device CB achieves better performance than the combination of SOP and CB in terms of both economic efficiency and loss reduction effectiveness, while maintaining voltages within safe operating limits, thereby enabling secure and economical operation of the distribution network.
