Description

technical field [0001] The invention belongs to risk assessment of real-time flood control dispatching of reservoirs, and in particular relates to a risk analysis and calculation method for real-time flood control dispatching of reservoirs considering error correlation. Background technique [0002] Reservoir real-time flood control scheduling is one of the important technical means for flood control and disaster reduction in the basin, and it can improve the efficiency of flood control projects with a small investment. However, in the process of real-time flood control scheduling of the reservoir, there are uncertain factors, including the forecast error of the reservoir inflow flow, the uncertainty of the reservoir outflow flow, and the uncertainty of the storage capacity of the reservoir. The uncertainty of water level brings risks to flood control decision-making. Therefore, the risk assessment of reservoir real-time flood control dispatching has important academic sign...
