Black-start scheme for charging-discharging-storage integrated station

The restoration of a power system after a black-out mainly includes network reconfiguration and load restoration. Reasonable black-start schemes play a major role to the fast restoration of power system after black-out. As a distributed power, charging-discharging-storage integrated station in islanding can participate in black-start when the grid falls in a full stop after failure. Basic configuration and power characteristics of the integrated station are presented firstly. This paper also analyses the advantages of integrated station as black-start source over the traditional black-start method. Then in accordance with the general principles of black-start, a black-start model and specific scheme for integrated station are developed, which meets power flow and system safety constraints. At last, the developed model is applied to a regional power system containing 16 integrated stations and the problem is solved with traversal algorithm. Black-start process for the regional power system is got and the feasi
