Abstract

The invention discloses an energy criterion-based method for generating a flood control optimization dispatch plan for a mixed reservoir group, the method comprising: selecting a mixed reservoir group and corresponding downstream protection objects; performing particle swarm coding; and setting each reservoir in the mixed reservoir group Constraint conditions; Calculate the fitness value of each particle in the first generation of particle swarm; Use the particle swarm algorithm based on the inertia weight of the decaying cosine curve to iteratively cycle and update the particles; Calculate the fitness value of each particle in the new generation of particle swarm until When the optimization conditions are satisfied, the flood control optimal dispatching scheme of the mixed reservoir group is output. The present invention adopts the particle swarm algorithm based on the inertia weight of the decaying cosine curve, which overcomes the disadvantage that the existing particle swarm algorithm is easy to fall into the local optimum, and enhances the global and local search capabilities. Under the condition of ensuring the safety of the downstream, the flow of the flood control reservoir group is greatly reduced, and the risk of flood control is greatly reduced.

Description

technical field

[0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to an energy criterion-based method for generating an optimal dispatch scheme for flood control of mixed reservoir groups. Background technique

[0002] Flood disasters in my country are sudden, frequent and uncertain, and their threat to human survival and development is relatively serious, especially the disasters caused by super-standard floods are even more immeasurable. The flood control engineering system needs to formulate corresponding scheduling schemes for reservoir projects. However, in the real-time scheduling of joint flood control, it is affected by many factors, and the reservoir group involves more elements. Especially for mixed reservoir groups, the correlation is more complicated.

[0003] Due to the complexity and close correlation of the system, the use of optimization theory for regular identification often results in a large op...
