摘要
随着我国电力体制改革的不断深化,常用的安全约束经济调度模型不能满足"三公"调度计算周期的要求,且为克服电量直接交易对"三公"调度的影响,提出考虑"三公"调度的两阶段年滚动发电计划优化模型。第一阶段建立考虑直接交易及"三公"调度的滚动机组组合优化模型,在年度剩余周期内优化机组组合及电量计划;第二阶段建立考虑电厂日负荷率均衡的发电计划优化模型,避免电厂日平均负荷率的快速变化。某省级电网的实际算例仿真结果验证了所提模型的正确性及方法的有效性。
With the deepening reform of electric power system in China,the commonly used security constrained economic dispatching model cannot meet the calculation period requirement of open and impartial dispatching,and in order to overcome the influence of electric power direct trading on open and impartial dispatching,a two-stage optimization model for annual rolling generation scheduling with the consideration of open and impartial dispatching is proposed. In the first stage,the optimal rolling unit commitment model considering the direct trading and open and impartial dispatching is built,which optimizes unit commitment and power generation schedule in the annual residual period. In the second stage,the generation scheduling optimization model considering the balance of daily load rate of power plant is built to avoid the rapid change of average daily load rate. The simulative results of a practical provincial power grid verify the correctness of the proposed model and the effectiveness of the proposed method.
