The multi-terminal flexible distribution switch (FDS) is used as a device for dynamic power regulation, which is beneficial to the operation optimization of the active distribution network (ADN). Based on the topology of distribution network with FDS access and the mathematical model of three-terminal FDS, a dynamic optimization model for active and reactive power coordination of distribution network with FDS is established: constructing a multi-time scale active and reactive scheduling architecture to optimize the objective function of network loss and voltage, and consider the operating constraints that take system security and cross-section action constraints into account. In order to improve the solution efficiency and relaxation precision of multi-section tidal model, an optimization method for second-order cone programming and nonlinear programming is proposed, and the test results are obtained by using SCIP and other algorithm packages. Finally, based on the actual engineering data, the simulation test is carried out in the distribution network system with three-terminal FDS. The results showed the positive effects of FDS on power quality improvement, operation strategy optimization and intelligent distribution of power flow in ADN, and verified the stability and computational efficiency of the proposed method.
