摘要：
SOP(Soft Open Point) provides new ideas for the consumption of high penetration of photovoltaic in distribution network, so the security boundary of rural network is incorporated into the planning model of distribution network to optimize and research the hosting capacity of DPV(Distributed PhotoVoltaic). The improved security boundary model considering the loss of the rural network is derived and analyzed, and its linear expression is proposed. The SOP principle is explained and the mathematical model is built for distribution network planning. Then, taking the maximum of DPV hosting capacity as the objective, the active-reactive power coordinated optimal model of DPV and SOP considering the improved security boun-dary and active management measures is proposed. Meanwhile, SOP and other parts in this model are linea-rized by introducing linear approximation, so the original model is transformed into a mixed integer linear programming model, and GAMS is used to solve the optimal problem. Finally, case studies are carried out on a 51-bus rural network to illustrate the effectiveness and correctness of the proposed model and method, and the impacts of security boundary, active management measures and SOP capacity on the maximum hos-ting capacity of DPV are analyzed. © 2022, Electric Power Automation Equipment Press.
