基于Critic-Shapley法的梯级水电站补偿效益分摊

Sharing Compensation Benefits of Cascade Hydro-power Stations Based on Shapely and Critic Value Method

为使梯级水电站补偿效益分摊结果趋于合理化,也即既保证效益最大化,又兼顾公平性,最大限度地调动梯级各电站参与联合调度的积极性,将Critic权重分析法与Shapley值法结合,构建了Critic-Shapley模型,将Critic-Shapley法与其他方法进行比较分析,并将其应用于某流域梯级中的三级电站补偿效益分摊中,为实现整个梯级的联合调度提供参考。结果表明:该方法不仅考虑了效益分摊的公平性,同时兼顾了各个电站之间的差异性,即电站自身的装机容量、保证出力、多年平均年发电量和有效库容等个体特征,分摊结果更趋于合理,有利于调动龙头电站及下游各级电站参与梯级联合调度的积极性,在实现流域梯级联合调度的同时保证效益最大化。

To make compensation benefit distribution of cascade hydro-power stations more reasonably and mobilize the stations’ enthusiasm participating in joint operation,that is,to make the benefits maximum and take the fairness into consideration,the combination of the Critic Weight Analysis Method and Shapley Value Method is proposed in this paper. The Critic-Shapley model is established by comparing other methods,which is applied to compensation benefits sharing three hydro-power stations in a basin cascade,as a reference for operating the joint. The results show that this method not only takes the fairness of benefit sharing into consideration,but also focuses on the differences between the stations,such as installed capacity,guaranteed output power,the annual average generating capacity and effective storage capacity. The distribution results are relatively fair and reasonable. In particular,the enthusiasm of leading power plant and downstream power plants at all levels participating in joint operation is mobilized,which is in favor of achieving the joint operation and maximum benefits of basin cascade.
