Abstract A new method is presented to restore the power system based on dynamic programming (DP). After isolated a fault, the out-of service area, which is constructed of load nodes could be divided into several groups, each has one contact branch used for load distribution. These groups sharply decrease the number of calculation loops. According to the different restore orders of the load nodes, operation sequences are produced, which turn the restore problem into a node-string choice. Based on a DP method, operation sequences are used to build a multiple-stage decision model, each contact branch is calculated as one stage, the algorithm is designed to transfer and restore the largest load capacity by optimal choice of the node-string. In each stage, the calculation process records the optimal state and lists the decision variable. The optimal result is obtained at the final stage. This method can be used to power service reconfiguration, when the power capacity is not enough to support all of the out-of service nodes, reducing the time of outage and improve the reliability of system. The proposed method is validated by simulation methods.
