Two-stage Distribution Network Reconfiguration Method Considering Load Type and Overload Rate

In the operation of the distribution network, some network lines may be overloaded. In order to solve the problem, this paper proposes a distribution network reconfiguration model considering load type and network overload rate. First, a two-stage optimization model that takes the established load type into account and the purpose of this model is that transferring important loads into the line with a lower heavy load rate according to the load level. Then considering that the system topology will change with the load type, a new distribution network topology analysis algorithm is given in this paper. Finally, in order to improve the convergence performance, this paper choose two-stage optimization model solved by genetic-gray-wolf algorithm. The simulation is carried out in the IEEE 33-Bus System. The results show that the model and algorithm have good results and convergence.
