摘　　要：为解决我国沿海地区大规模风电接入电网场景下对台风灾害鲁棒性不足的问题,提出一种计及台风的含高渗透率风电大电网多时间尺度防御调度策略。首先,根据台风气象数据建立台风灾害下可调度风电资源评估模型及典型电网元件故障率模型,生成台风灾害下电网故障场景;其次,考虑台风场景下风电出力及故障情景,提出电网失负荷和电网风险指标量化的电网故障损失及概率,分析电网的风险成本;进一步,根据响应速度及能量时移特性对电网的多源调度资源进行分类,以电网风险成本及运行成本之和最低为目标函数构建多源电网多时间尺度防御调度模型,并应用改进海鸥算法对模型进行求解。最后,通过IEEE-39节点算例结果表明,所提出的防御调度策略能协调源-荷的灵活资源,提高电网面对台风灾害的鲁棒性。In order to solve the problem of insufficient robustness to typhoon disasters under the large-scale wind power access grid scenario in coastal areas of China,this paper proposes a multi-time scale defensive scheduling strategy for high wind power penetration gird after taking typhoons into account.Firstly,according to the typhoon meteorological data,a model of dispatchable wind power resources and the failure rate of grid components under typhoon disaster is established to generate a grid failure scenario under typhoon disaster.Secondly,the wind power output and failure scenarios under typhoon scenarios are taken into consideration,then the grid loss of load and grid risk indicators are proposed to quantify grid failure loss and probability,and the risk cost of the grid is analyzed.Furthermore,the multi-source grid dispatching resources are classified according to the response speed and energy time-shift characteristics,a multi-source grid multi-time scale preventive control model is constructed with the lowest grid risk cost and operation cost as the objective function,and the model is solved by the improved seagull algorithm.Finally,the IEEE-39 node arithmetic results show that the proposed defensive scheduling strategy can coordinate source-load-side resources and improve the robustness of the grid in the face of typhoon hazards.
