Abstract

Tidal pumping station pumps would consume lots of energy for pumping massive water. This paper provides an effective method to optimize operating schedules of the tidal pumping stations. A multi-objective model was proposed to minimize the total switching times and energy power. In the model, sub-periods are divided according to heads. A classical tidal pumping station, which mainly serves for the China's South to North Water Transfer Project, is performed as a case. As the energy consumption per unit pumped decreases, the switching times increases, and the operational reliability of the T-PS decreases. The optimal operation scheme reduces the switching times by about 58.824% and saves the energy consumption per unit pumped by about 3.803%, respectively. Therefore, the optimal operation scheme not only has excellent safety but also effectively reduces the operation energy consumption. Thus, this paper could provide effective optimized operation schedules for tidal-pumping stations.
