Abstract: Difficulties in benefit distribution for optimal joint operation of cascade reservoirs are analyzed. Considering the limitation of the Shapley value method, a new benefit distribution method based on information entropy is developed and applied to seven cascade reservoirs in the Wu River basin. Compared to the Shapley value and single-index allocation methods, this method needs a smaller set of data and is more efficient in calculations; its results are more equitable and reasonable, motivating managers to participate joint reservoir operation and improving hydropower resources utilization efficiency.
