Abstract:Faced with the difference in dispatch characteristics of controllable resources and the strong coupling of active and reactive power, the distribution network is facing many challenges in how to realize the coordinated operation of many resources and the efficient solution of the model. To solve the above problems, an ADN active-reactive coordination operation and efficient solution method considering the multi-period operation characteristics and reactive power adjustment ability of adjustable resources are proposed. Firstly, based on the second-order cone relaxation and linearization modeling technology, the optimization model is transformed into MISOCP. Further, based on the "ε-relaxation" method, the second-order cone is relaxed by polyhedron, and the model is transformed into a 0-1 MILP that can be efficiently solved. Finally, based on the IEEE 33-node power distribution system, it is verified that the proposed method can balance the accuracy and efficiency of the model. Meanwhile, on the basis of realizing the full consumption of WT and PV, the purpose of saving energy and reducing voltage levels is achieved.
