Radial Distribution System Reconfiguration in the Presence of Distributed Generators

A distribution network reconfiguration model with wind power generators is proposed, and an improved genetic algorithm is applied to minimize active power loss. Forward and backward sweep approach is adopted to calculate the power flow. In addition, the strategy of searching random spanning trees is used to ensure the radial structure of network in the process of reconfiguration. Simulation results show that the proposed method can reduce the power loss and improve the voltage quality of distribution system.
