摘要：Storage energy is an important state to reflect overall energy store stored in cascade hydropower systems. It is a practical method to avoid abandoned electricity and power supply shortage in hydropower operation in power grid by energy storage to control the progress of reservoir storage drawdown and refill. In order to optimize the operation plan of cascade reservoirs under the cascade storage energy control, a model of long-term optimal operation of multi-reservoir system subjected to cascade storage energy is and a two-stage optimization algorithm for it is presented. The method achieves pre-dimensionality reduction by using iso-storage energy curves and dynamic programming Taking the cascade hydropower stations of Lancang River as the background, the results of case study that the proposed method can maximize the power generation benefit of cascade hydropower stations and improve the computational, and is suitable to resolve such problems in operation.
