Loss minimization using multi-stage evolutionary programming for network reconfiguration in distribution system: article

The occurrence of system loss due to line resistance in the distribution system can be minimized by changing its network reconfiguration. Therefore, network reconfiguration is an important issue for distribution system automation. The system loss minimization via network reconfiguration can be done by altering the topological structure of distribution feeders by changing open or closed status of sectionalizing and tie­switches to achieve different combinations of switching status. A stochastic optimization strategy of Multi-stage Evolutionary Programming MEP was proposed in this paper which can be used in distribution systems to solve network reconfiguration. The proposed method was simulated by using Matlab software 1111d verified in an IEEE 69 bus distribution sys
