Abstract: To optimize compensation benefit allocation schemes for cascade hydropower stations, we consider the stability of different schemes and the conditions of decision-makers affected by psychological factors, and suggest a propensity-to-disrupt (PTD) value for evaluating the stability. Then, we construct a decision-making index system that is based on the allocation proportion, power generation benefit, and PTD value of each hydropower station, and develop an improved ideal point decision-making based on the regret theory. This method along with the index system is verified through application to optimizing the compensation benefit allocation schemes for the cascade hydropower stations of Sanliping, Siping and Guoduwan in the Nanhe basin of the middle Hanjiang River.

Key words: compensation benefit allocation scheme, decision-making, stability evaluation, regret theory, ideal point method
