A long-term control method for cascade reservoirs based on long series optimized dispatch set
By establishing a long-series restored inflow collection and optimized scheduling model, combined with the hybrid PSO algorithm, the problem of inaccurate inflow forecasting in the medium- and long-term planning of cascade reservoirs was solved, thereby reducing scheduling risks and improving the completion of multi-dimensional utilization objectives, and providing reliable medium- and long-term control water level and output plans.

Abstract
The application discloses a long-term control method for cascade reservoirs based on long-series optimized scheduling sets, which comprises the following steps: establishing a restored data set, calculating reservoir storage influence, obtaining long-series restored inflow, performing optimized scheduling calculation according to the long-series restored inflow, and rolling determining the control water level and output of the cascade reservoirs according to the optimized scheduling scheme set; the application can obtain the long-term control water level and output plan of the cascade reservoirs, which has small scheduling risk, high multi-dimensional utilization target satisfaction degree, high reliability and conforms to the actual situation, and can be widely applied to production practice, especially the scheduling of large-scale cascade reservoir groups.
