| 摘 要： | 以金沙江中游梯级水电站群为例，结合电网需求，建立了基于负荷曲线运行的梯级水电站群短期联合发电优化调度模型，并采用逐次逼近法与逐步优化法的耦合算法对模型进行求解，比较分析了基于该模型的短期运行发电量效益。结果表明，梯级联合运行更符合电网调度需求，且在周调节基础上进一步日调节，综合效益增幅显著。 |
| 关 键 词： | 梯级水电站群 短期运行 电力负荷曲线 日调度 调峰调度 |

| Abstract: | Taking the cascade hydropower stations in middle reaches of Jinsha river for an example,the short-term generation optimal model based on load curve is established to meet the demand of power grid.The model is solved with coupling of dynamic programming successive method and progressive optimality algorithm.And then the short-term generation benefit based on the model is calculated and made a comparison.The results show that not only the cascade joint operation is more accord with the dispatching demand of power grid,but also the comprehensive benefits could improve more observably with the further daily regulation on the basis of weekly regulation. |
| Keywords: | cascade hydropower stations short-term operation power load curve daily scheduling peak regulation dispatching |
