摘　　要：在电力电量供应形势紧张的情况下,现有紧急中断负荷的调度方式,不仅给电网公司带来严重的经济损失,还对电网的安全稳定运行构成威胁。为此,将用电资源纳入电网的统筹调度,以电源规划、检修计划、需求预测、一次能源供给预测以及用电特性分析为基础,以中长期电力电量平衡为约束,以效益损失最小为目标,建立中长期发用电一体化调度模型。将所建模型转换为混合整数线性规划模型后,采用CPLEX求解器进行求解。最后,结合可中断负荷以及调减外送电两种用电调度措施,以包含13个梯级水电站和18个火电站的水火电力系统为例进行仿真,算例分析表明,该模型可在保证中长期电力电量平衡的同时,实现发电与用电的统一优化,进而提高系统运行的安全性和经济性。For the tightness of electric power and energy supply, current emergency scheduling of interrupting load not only brings serious economic losses to the grid company, but also poses a threat to the operation stability of power grid. In this paper, the consumption resources are consid- ered during the generation dispatching, and the mid-long term integrated generation-consumption dispatching model is built with the constraints of power-energy balance and the objective of minimum benefit loss based on the generation expansion planning, maintenance scheduling, demand fore- casting, energy supply forecasting and the electricity charac- teristic analysis. Then the model is converted into a mixed- integer linear programming model, which is solved by the CPLEX solver. In the end, a hydrothermal power system with 13 cascade hydropower stations and 18 thermal power plants is tested by taking into account both dispatching meas- ures of the interruptible load and out-going power reduction. Example analysis shows that the model can ensure the mid- long term power-energy balance, and optimize the power generation and consumption in unified way, which improve the safety and economy of system operation.
