摘　　要：近年来极端天气事件频繁发生,黑启动电源成为电网大停电后能否快速恢复的关键,对于缺乏抽水蓄能机组和水电机组的地区电网,文章提出有选择地对区域内的燃气-蒸汽联合循环机组进行黑启动改造,优化黑启动电源布点方案。文章结合极端天气对电网的影响,定义了线路恢复风险,建立了以最小化保底网架恢复时间和线路恢复风险为目标的黑启动电源布点双目标优化模型,在找出方案非劣解的基础上应用推广理想点法求得最终黑启动电源布点方案,并通过东莞地区电网的算例验证了该方法的有效性。Extreme w eather events happen more frequently in recent years,w hich make the black-start units become the key to the fast restoration after a blackout.For most regional pow er grids w ith few pumped-storage aggregates and hydropow er units,this paper proposes an optimal allocation of black-start pow er sources w hich come from the modified gassteam combined cycle units.In this paper,combined w ith the influence of extreme w eather on the pow er grid,the risk of line recovery is defined,and a bi-objective optimization model of black-start pow er source allocation w ith the goal of minimizing the recovery time and risk of the guaranteed pow er 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 pow er grid.
