中长期发用电一体化调度
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。
Abstract: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 considered 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 forecasting, energy supply forecasting and the electricity characteristic 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 measures 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.
