Regional Network Reconfiguration Algorithm for Loss Reduction and Loading Equilibrium

In the essence the network reconfiguration is a multi-objective optimization problem with the purpose of loading equilibrium among branches and loss reduction, especially,it is an important measure to implement energy-saving dispatching in regional power networks.To simultaneously consider the two indices of economy and security during the optimization,a synthetic model that considers network loss and loading equilibrium is built and an estimation formula for the variations of loss reduction and loading equilibrium indices caused by opening or closing single loop is derived.Based on the derived formula,a fast branch exchange algorithm for network reconfiguration,which can be used in the network reconfiguration considering both loss reduction and loading equilibrium,is proposed.Results of primary application of the proposed algorithm in a certain regional network show that the proposed method is available.
