金沙江下游—三峡梯级水库群调度运行补偿电量分配

为探究金沙江下游—三峡梯级水库群联合发电调度补偿电量及补偿规律,以溪洛渡、向家坝、三峡、葛洲坝水库为例,分别建立了单库优化调度和梯级水库联合调度模型,并以长系列历史径流为输入进行调度模拟,在此基础上,考虑各水库参与联合调度的贡献值,提出基于补偿电量贡献值的贡献系数计算方法,进行了水库间和梯级间联合调度补偿电量分配,获得了不同水库间的补偿电量,为金沙江下游—三峡梯级水库群管理决策提供理论支撑与技术支持。

Compensation of Electricity Distribution for Dispatching Operation of Cascade Reservoirs from Lower Reaches of Jinsha River to Three Gorges

In order to explore the compensation electricity and compensation law of joint generation operation of cascade reservoirs from the lower reaches of Jinsha River to the Three Gorges, taking Xiluodu Reservoir, Xiangjiaba Reservoir, Three Gorges Reservoir and Gezhouba Reservoir as the objects, single reservoir optimal operation model and cascade reservoirs operation model were established to simulate operation with a long series of historical runoff as the model input. Considering the participation of each reservoir in the joint operation and contribution value, the calculation method of contribution coefficient was put forward based on the contribution value of compensation power. The distribution of compensation power for joint operation between reservoirs and cascades was carried out, and the compensation power between different reservoirs was analyzed, which provided theoretical support and technical support for management decision-making of cascade reservoirs from the lower reaches of Jinsha River to the Three Gorges.
