一种应对超强台风的电网在线预防控制方法
An Online Preventive Control Method for Power Grids to Cope with Super Typhoon
摘要
Abstract
In recent years,typhoon disasters have occurred frequently worldwide,posing a serious threat to the safe and stable operation of power systems.When a super typhoon passes through,it can cause a large number of power line faults and trips,severely damaging the structural integrity of the power grid and directly leading to widespread power outages.In addition,it can trigger system power flow shifts,significantly increasing the risk of cascading interruption and further aggravating disaster losses.To reduce such losses caused by super typhoons,this paper analyzes the operational statistics of the power grid during the passage of typhoon Yagi over Hainan in 2024 and proposes an online preventive control method to cope with super typhoons.Considering the N-1 security constraints of the power grid,the objective constraints are introduces to ensure N-2 transmission line security for power plants within the core typhoon-affected area.An online preventive control model for coping with super typhoon is constructed to optimize and adjust generator output,tripping and load shedding so as to eliminate equipment overloads and reduce the risk of cascading outages from contingencies,thereby mitigating disaster losses caused by super typhoons.The proposed method is used for simulation on Hainan power grid real data during typhoon Yagi in 2024.The results verify the effectiveness of the proposed method.关键词
