Abstract
A novel ecological operation chart and coordinated management policy for the cascaded hydropower system are proposed in this study, in which limited ecological curves were introduced to balance long- and short-term ecological requirements and hydropower benefits. A case study is performed in Xiaowan-Manwan reservoirs on the Lancang River. The proposed operation charts lead to a 0.77% increase in electric production and a 0.05% increase in ecological conservation degree, as well as alleviation in the ecological damage frequency from 19.72 to 10.28%. The operation strategy and management policy are further discussed including trade-offs among competing objectives, monitoring, an early warning system, and the multiparty platform in practical operation.
