摘　　要：针对三峡梯级电站在系统负荷图上峰、平、谷各时段的优化运行,提出了基于分时电价的三峡梯级电站日前优化数学模型;仿真实验研究表明,该模型所确定的调度方案合理可行,效益显著。通过比较在单一电价模式及分时电价情形下三峡梯级电站在日前电力市场出力过程得出,分时电价模型能够使得梯级电站出力更加可靠,综合利用水资源,具有实际应用价值。According to Three Gorges cascade hydropower stations' optimal schedules at different load hours including peak and valley load hours, a time-of-use (TOU) electricity price based day-ahead optimized mathematical model for Three Gorges cascade stations is proposed. Simulation results show that the schedules determined by the proposed model are reasonable and feasible and evident economic effect can be obtained. Comparing the power output processes of Three Gorges cascade hydropower stations in day-ahead electricity market under fixed electricity price mode with those under TOU mode, the gained conclusion is that the TOU model, by which the outputs of cascade hydropower stations become more reliable and the water resources can be comprehensively utilized, is practicable.
