A DPSO-Based Parallel Sectionalized Restoration Scheme for Power System

As the development of the power system is moving towards an intelligent direction, the probability of power system blackouts is effectively reduced. However, blackouts cannot be completely avoided due to many uncertainties. For a large-scale power system, there may be many generators with black-start capability and external power sources, which can be used as black-start power sources after a blackout. This paper presents a discrete particle swarm optimization (DPSO) system sectionalizing method, by which the entire blackout area can be sectionalized into several subsystems. Simulation results on the New England 39-bus system verify the effectiveness of the proposed parallel restoration scheme.
