Optimal Operation of Intake Water Pumping Station swith Peak-valley Price and Regulation of Clearwells

Studying the optimal operation of the intake pumping water station has a guiding significance for pump station energy-saving.In regard to the operational characteristics of intake pumping water stations,a model including constant speed or two-speed pumps is applied for the optimal operation of the intake pumping water stations.The model is established with the minimum day total operational cost as objective function.The effect of peak-valley price and regulation of clearwells on the day total operational cost of the intake pumping water station are taken into consideration in the optimal operation.The model is computed with the method of dynamic planning.Finally,the calculation results of the practical example show that the intake pumping water station after optimal operation can be effectively achieved to run with peak shifting and the full advantage of regulation of clearwells to respond to the peak-valley price in the case of the unchanged types of the original pumps and meeting the requirements of water suppy equally.And the daily total operational cost of the intake pumping water station decreases significantly.This verifies the established optimal operation mathematical model is reasonable and effective.It is of significance for energy-saving operation of similar water pumping stations.
