Power grid system operation standby time-space quantitative evaluation method and device

The invention provides a power grid system operation reserve time-space quantitative evaluation method and device, and the method comprises the steps: enabling a target function of an operation reserve time-space quantitative evaluation algorithm model to be minimum in difference between the scale information of a maximum accident and the capacity information of an available reserve unit, and enabling the model not to pre-define a regional reserve demand, and instead, the area reserve capacity is used as a model variable, namely the minimum reserve capacity or the limited maximum reserve capacity possibly required in a certain area, so that the area reserve capacity can be delivered during scheduling. And meanwhile, the transmission limitation constraint after deployment of the standby unit is incorporated into the model, so that the problem of a standby maximum limited value is solved. 本申请提供了一种电网系统运行备用时空量化评估方法及装置，本申请的技术方案中，运行备用时空量化评估算法模型的目标函数为最大事故的规模信息与可用备用机组容量信息之差最小，模型不预先定义区域备用需求，而是将其作为模型变量，即可能在某区域内所需的最小数量备
