Abstract After large scale blackout of interconnected power system, an effective partitioning scheme with logical parallel recovery strategies would greatly speed up the entire restoration process and promote the probability of successful recovery. In this paper, a new method of optimizing the system partitioning schemes considering the successful rate of node restoration is proposed. With the uncertainty of transmission lines and the complexity of power network structure taken into account, the successful rate of node restoration is calculated by identifying the minimum path sets of the node. Based on this, a new partitioning criterion function is established to determine the optimal belonging zone of the node. According to the starting characteristics of units and the operational parameters of transmission lines, the efficiency of subsystem reconfiguration, the time variance of different zones and the total time it took to form the skeleton network could be obtained. An optimization function is established and the cross particle swarm optimization algorithm is employed to realize the final optimization of the partitioning schemes.
