Reconfiguration for decreasing power losses, improving voltage stability and network security index of distribution systems considering stochastic optimization

The purpose of the network reconfiguration in literature is to reduce power losses and increase reliability by changing the status of switches, but in this paper, the reconfiguration with considering power losses, voltage stability, and network security index (NSI) is developed and we solved the reconfiguration problem with new objective functions. Also, the stochastic optimization of load and generation is considered that scheduled to be ۲۴-hour and seasonal. In addition to ۲۴-hour scheduling from distributed generation (DG), resources with random distribution are used. In this paper, the goal is the effect of reconfiguration on the desired targets, as well as simulating the reconfiguration and the placement of DG sources simultaneously, and we want to examine the impact of this simulation on the performance of the system. To assess the capabilities of the proposed method, simulations are carried out on an IEEE ۳۳-bus radial distribution system. Simulation is performed in ۶ scenarios. The obtained results demonstrate the effectiveness of the proposed method.
