In this paper, a day‐ahead active and reactive power coordinated optimization strategy for active distribution networks (ADNs) with dynamic reconfiguration and soft open point (SOP) is proposed. Firstly, the model of dynamic reconfiguration of distribution networks and SOP are established. Afterward, the day‐ahead active and reactive power coordinated optimization model of ADNs is established to minimize ADNs daily operation cost with consideration of the operation constraints of distributed generation, reactive power compensation equipment, dynamic reconfiguration of distribution networks and SOP. Then the model is converted into a mixed‐integer second‐order cone programming problem by using the Big‐M method and the second‐order cone relaxation and afterward is solved by YALMIP and CPLEX. Finally, the effectiveness of the proposed second‐order cone optimization model is validated by a modified IEEE 33‐node power distribution network.
