摘要：

Local outages in a power system are more likely to occur compared with a system wide blackout. However, most existing research is focused on developing restoration strategies for a global blackout in a power system, and less attention has been paid to local power system restoration which occurs more frequently. Given this background, a local power system restoration strategy considering critical load pickups is presented. Firstly, the characteristics of local power system restoration are discussed, and restoration paths are generated based on the topology of the outage area. Secondly, the restoration paths causing over-voltage problems as well as the unnecessary paths are removed. Then, an optimization model is developed for determining restoration subsystems and restoration paths. Compared with most of the existing methods in which subjective weights are required for the lines and buses to be restored, the proposed method can attain more reasonable restoration strategies. Finally, the modified New England system is employed to demonstrate the effectiveness of the developed method. © 2013 State Grid Electric Power Research Institute Press.
