For the planning of the guaranteed power grid, only the operation capacity of the target grid is considered. The recovery process and steps of the backbone grid are not considered enough, which leads to two defects: the minimum guaranteed power grid is not conducive to the unit recovery and the recovery time is too long. In this paper, a method of constructing the grid with the specific recovery process is proposed. Considering the influence of the grid structure and the position of the black start power supply on the recovery steps, the recovery success rate and the recovery time of the grid, the optimization of the grid structure of the guaranteed grid can meet the demand of power supply and at the same time make the recovery of the target grid less time-consuming and achieve a higher recovery success rate in the event of a blackout. In this method, two aspects are considered: the power failure recovery scenario in the recovery process of the target grid and the normal power supply scenario, reflecting the power supply performance after the recovery of the target grid. In the normal power supply scenario, a three-objective optimization model including power supply capacity, smooth transmission and safety margin is constructed, with power supply capacity and safe operation as constraints. In the scenario of power failure recovery, the process of power grid recovery and the mechanism affecting the success of recovery are analyzed to form the line recovery index. The Dijkstra algorithm is used to search for the optimal recovery path and calculate the recovery index, so as to reoptimize the backbone power grid. The validity of the method is verified by standard and practical examples.
