【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]:Under the condition of tight power supply, the current dispatching mode of emergency interruption load not only brings serious economic losses to the power grid companies, but also threatens the safe and stable operation of the power grid. Power resources will be integrated into the overall dispatch of the power grid, based on power planning, maintenance plan, demand forecasting, primary energy supply prediction and power characteristics analysis, with the medium and long term power balance as a constraint. Taking the minimum benefit loss as the goal, a long-term integrated dispatching model of power generation and power supply is established. After the model is converted into a mixed integer linear programming model, CPLEX solver is used to solve the problem. Combined with two kinds of power dispatching measures, interruptible load and external power transmission, the hydro-thermal power system including 13 cascade hydropower stations and 18 thermal power stations is taken as an example. The model can achieve the unified optimization of power generation and power consumption while ensuring the medium and long term power balance, thus improving the security and economy of the system operation.

【正文快照】： 0引言近年来,我国电网装机容量、省内及外送电负荷都得以较快发展。虽然装机规模逐年增长,但由于用电需求增长更快,电源建设仍然相对滞后于用电需求的增长,并逐渐凸显出电力供需的矛盾[1]。2010年贵州电网因执行节能减排政策安排了部分火电机组进行脱硫改造,加上来水偏枯,使得
