多主体梯级电站补偿效益分摊的改进Raiffa法

Improved Raiffa Method for Compensation Benefit Allocation of Multi-Agent Cascade Power Stations

摘要: 针对传统效益分摊方法在多主体梯级水电站联合调度效益分摊时的局限性，提出改进Raiffa法效益分摊方法，对乌江流域六座梯级水库联合优化调度的补偿效益分摊问题进行求解，并与单指标法、信息熵法、熵权法等分配方法进行对比，最后采用分配策略倾向分析对分摊结果进行评定。乌江梯级实例结果表明，改进Raiffa法计算效率高、分摊结果好，梯级多业主情形下可以得到公平、合理且稳定的效益分配结果。该方法能够为解决多主体梯级水电站联合调度效益分配问题提供新的思路和方法，调动梯级电站联合运行的积极性，提高水资源利用率。

Abstract: Addressing the limitations of traditional benefit allocation methods in distributing the joint operation benefits among multiple stakeholders in cascade hydropower stations, this study proposes an improved Raiffa method for benefit allocation. The method is applied to solve the compensation benefit allocation problem arising from the joint optimal operation of six cascade reservoirs in the Wujiang River basin. The allocation results are compared with those obtained using single-indicator methods, the information entropy method, and the entropy weight method. Finally, an allocation strategy tendency analysis is employed to evaluate the allocation outcomes. The case study of the Wujiang cascade demonstrates that the improved Raiffa method offers high computational efficiency and produces superior allocation results. Under multi-owner cascade scenarios, it yields fair, appropriate, and stable benefit distribution outcomes. This method provides a new approach for solving the benefit allocation problem in the joint operation of multi-stakeholder cascade hydropower stations. It can mobilize the enthusiasm for cascade joint operation and improve water resource utilization efficiency.
