摘　　要：为解决配电网控制分散、控制元件可调范围小等问题,将潮流路由器(Power Flow Router, PFR)应用于配电网。提出了一种适用于配电网的含潮流路由器的改进支路潮流模型,并基于此建立了含PFR的配电网最优潮流模型。对模型进行二阶锥松弛,并采用Gurobi等商用算法包对松弛后的模型进行求解。为考虑负荷和分布式电源出力的不确定性,提出了一种拉丁超立方抽样和二阶锥规划相结合的概率最优潮流求解方法。采用修订的IEEE33节点系统验证了所提方法的有效性。In order to solve the problem of limited control range of control elements and scattered control pattern of distribution networks,Power Flow Router(PFR)is applied in distribution networks.An improved branch flow model with power flow routers in distribution networks is proposed and an optimal power flow model including PFR is constructed.Second-order cone relaxation is used to relax the model and the relaxed model is solved by using the commercial algorithm package such as Gurobi.Furthermore,a method,which considers the uncertainty of load and distributed generation’s output,is presented based on the combination of Latin hypercube sampling and second-order cone programming.The revised IEEE 33-bus system verifies the effectiveness of the proposed method.
