摘要：
In the preliminary stage of power system restoration, shortage of black start resources delays the procedure of restoration. With various types of resources accessed in distribution systems (DSs), it is possible to utilize active DSs to support transmission system (TS) restoration through bottom-up strategy, accelerating black start. First, the idea of coordinated restoration of TS and DSs is proposed, the capabilities of DSs to contribute into the bottom-up restoration strategy are analyzed, and the supporting patterns are clarified. Second, considering the generator cranking power of TS and generation resources of DSs, external characteristics of DSs are defined, together with modeling of DSs external characteristics. Then, minimizing the total starting time of generators, a mixed-integer linear program of synthetic optimal decision-making for parallel restoration sectionalizing and generator start-up sequence considering coordinated restoration of TS and DSs is built. The effectiveness and superiority of the proposed method are verified based on an actual power grid case of China. © 2024 Chin.Soc.for Elec.Eng.
