In this paper, the authors propose a method for determining the load restoration sequence taking into account the cost of interruptions electrical service, under conditions where the time for operating circuit breakers to restore a load exceeds the time required to increase the generators’ electrical power up to meet the demand. To find the suboptimal solution to this problem, it is formulated as a nonlinear 0-1 programing, and it can be solved by the lexicographical enumeration procedure. An example demonstrates that the proposed method is effective for restoring the load, because the cost of interruptions electrical service using the suboptimal solution of the proposed method is lower than　that with the traditional solution which uses load priorities. It seems to he impossible to apply the proposed method to real large power systems through a real-time on-line computer, because the solution by this method takes too much computing time, unless a more effective bounding algorithm can be developed. Nevertheless it is effective to apply the proposed method to the determination of the load restoration sequence for some hypothetical faults in power systems through a off-line computer.
