A method for operation control of pressurized pipeline cascade pumping stations based on energy dispatch optimization

Abstract

This invention discloses a pressurized pipeline cascade pumping station operation control method based on energy dispatch optimization, belonging to the field of water conservancy engineering technology. The method includes the following steps: S1, determining the basic parameters of the pressurized water conveyance system cascade pumping stations, including pumping station operating parameters, pipeline and tunnel hydraulic constraint parameters, deriving energy consumption-related parameters based on the pumping station unit head-flow-power characteristic relationship, and adapting the hydraulic connection relationship between the pressurized pipeline and tunnel; S2, constructing an optimization model based on the basic parameters with the objective of minimizing total energy consumption under full-cycle water supply control. The pressurized pipeline cascade pumping station operation control method proposed in this invention significantly improves the overall flow regulation flexibility of the system by accurately tapping the regulation potential of power frequency and variable frequency pumping stations in the cascade pumping stations. It effectively addresses the problem of insufficient regulation potential tapping in traditional methods, constructs a unified flow constraint system, and enhances the adaptability of the technical solution to complex engineering environments.
