Abstract: A forecast operation method for lowering the reservoir flood limited water level considering forecast uncertainty is disclosed. The flood forecast feasibility of a reservoir controlled basin is analyzed, and the principle of maximum entropy is adopted to identify forecast error distribution; A framework of operation rules for lowering the flood limited water level at the flood rising stage is formulated by using an idea of pre-release, and the forecast operation framework is optimized to obtain forecast operation solution optimization point sets; All optimization point sets that achieve the upstream and downstream flood control safety in case of maximum forecast errors are screened out from the forecast operation solution optimization point sets; and finally, in comprehensive consideration of forecast errors and different preferences of decision makers, the optimal forecast operation solution points are evaluated by using a binary comparison method and a fuzzy optimization model.

Abstract: A method and system for ecological operation of total phosphorus (TP) export of a cascade hydropower station are provided. The method includes: integrating total power generation and TP export of the cascade hydropower station into a single operation objective, and obtaining an operation objective under different weight ratios; optimizing the obtained operation objective; and obtaining a water level operation process corresponding to total power generation and TP export under the current operation objective through the optimized operation objective. The present invention alleviates an ecological and environmental problem caused by the construction of the hydropower station from a water quality mechanism, and can be widely used, for example, in the ecological optimal operation of cascade hydropower stations in a river basin.
