Mixed integer programming calculation method for simultaneous switching decision of multiple devices in event process

The invention provides a mixed integer programming calculation method for simultaneous switching decision of multiple devices in an event process. The mixed integer programming calculation method includes the steps: extracting the transient process of the event process from the beginning to the steady state, establishing a power vector for an active power load characteristic, introducing a two-dimensional 0-1 variable to establish a mixed integer programming calculation method (MILP), comparing a load equipment power combination with a measured value, and obtaining a load model of the event byusing Cplex optimization. 本发明提供一种事件过程多设备同时投切决策的混合整数规划计算方法，将事件过程从开始到进入稳态的这一暂态过程提取出来，通过对有功功率负荷特征建立功率向量，引入二维0-1变量建立混合整数规划计算方法(MILP)，将负荷设备功率组合与实测值进行比较，使用Cplex优化得出该事件的负荷模型。
