Extreme weather events happen more frequently in recent years， which make the black-start units become the key to the fast restoration after a blackout. For most regional power grids with few pumped-storage aggregates and hydropower units， this paper proposes an optimal allocation of black-start power sources which come from the modified gas-steam combined cycle units. In this paper， combined with the influence of extreme weather on the power grid， the risk of line recovery is defined， and a bi-objective optimization model of black-start power source allocation with the goal of minimizing the recovery time and risk of the guaranteed power grid is established. The improvement of TOPSIS method is applied to solve this model on the basis of the non-inferior solution. The effectiveness of this method is verified by an example of Dongguan regional power grid.
