Abstract

After a power system is subjected to a blackout, parallel restoration is an efficient means to speed up the restoration process. The system sectionalizing strategy consists of determining the proper splitting points to sectionalize the entire blackout area into several subsystems, so that parallel restoration can be carried out within the subsystems. For a large-scale power system, this system sectionalizing problem is quite complicated when considering black-start constraints, generation/load balance constraints, and voltage stability constraints. This paper presents an ordered binary decision diagram (OBDD) -based system sectionalizing method, by which the splitting points can be found quickly. Simulation results on the IEEE 118-bus test systems show that the method can successfully sectionalize the system into subsystems satisfying black-start constraints, generation/load balance constraints, and voltage stability constraints.
