Skeleton-Network Reconfiguration Based on Node Importance and Line Optimization

In power system restoration process, power transmission network reconstruction problem is studied. Using a complex network related theory, putting forward a comprehensive consideration node importance and transmission lines optimization network reconfiguration method. This method considers the influence of shunt capacitance on node importance, realizes the weighted power transmission network reconfiguration, the index make both important node and Line Optimization realize, achieveing the whole optimization of the reconstruction network. The genetic algorithm method with characteristics of global optimization and handling the discrete variables easily and effectively is employed to solve this problem. Finally, IEEE39 test system is applied as benchmark to demonstrate the effectiveness and validity of the proposed method.
