Abstract: In view of the fact that there are different interest or dispatching bodies in a hydropower station, in order to solve the cooperative dispatching problem of sharing a reservoir water among different bodies, this paper constructs a medium and long term optimal dispatching model of hydropower station with maximum overall power generation under different main constraints. The operation mode of loan-payback is introduced into reservoir operation for the first time, and the short-term cooperative dispatching of "one reservoir and two plants" is realized. Finally, taking Xiluodu Hydropower Station on the Jiasha River as an example, the medium and short term calculation and verification are carried out, and compared with the actual operation of history. The results show that it accords with the practical application with the error of less than 5% and can be used for practice. The model embodies the principles of fairness and justice, compensation for contract breach, equal allocation of power generation benefits among all parties.
