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.
