Optimal Generator Start-up Sequence with Active Distribution Networks Considering Recovery Path

The recovery process of power system after blackout can be divided into three stages: generator start-up, grid reconfiguration and load restoration. This paper focuses on generator start-up and proposes a new optimization model of generators start-up sequence (GSS). Recovery path constraints are formed considering line capacitance for avoiding node overvoltage and node importance for facilitating the next two recovery process. The participation of active distribution network is also considered in the model, and various constraints are formed according to characteristics of active distribution network. The GSS problem is transformed into MISOCP model. This paper verifies the effectiveness of recovery path constraints and the advantages of participation of distribution network in GSS problem in T39D33 case.
