The thermal power generation units possessing the function of fast cut back (FCB) that they can serve for auxiliary power consumption during external faults in power grid and fast supply power after external faults cleared, so they are excellent power source for black start. The influences of FCB units on power grid restoration are analyzed, and taking the shortest restoration time of grid units as the objective and the startup time, starting power, energizing time of transmission lines as constraints, a model of optimal locating scheme for FCB units is established. To improve the computing efficiency, the ordinal optimization is led in to ensure obtaining good enough locating scheme for FCB units with as high as enough probability. The effectiveness of the proposed model and algorithm is validated by simulation results of IEEE 118-bus system and a certain actual power grid. Simulation results show that reasonable locating scheme of FCB units can speed up the restoration of power grid.
