To further improve the safety and reliability of the new energy grid planning process, reduce the risk of maintenance accidents. Aiming at the regional power grid with wind power collection substation, this paper proposes an optimization planning model for grid wind farm maintenance and power outage uncertainty based on decomposition and coordination method. The model considers the technical measures and operational status to meet the uncertainty of grid wind farm maintenance and power failure. And an optimization model solving strategy based on combination of tabu search and sensitivity analysis is established. Finally, the proposed model method is applied to the optimization planning of the uncertainty of maintenance and power failure of urban power grids in a certain area. The analysis results verify the effectiveness and practicability of the method described in this paper.
