A model predictive control strategy for load shifting in a water pumping scheme with maximum demand charges

Abstract

This paper defines and evaluates a model predictive control strategy with binary integer programming optimization for load shifting in a water pumping scheme. Both time-of-use and maximum demand charges are considered in the control model. The control model yields near optimal switching times which reduce time-of-use and maximum demand based electricity costs. Both the time-of-use and maximum demand charges have a significant effect on the optimal switching times.
