Upper and lower bounding procedures for the optimal management of water pumping and desalination processes

摘要

We consider the problem of water production optimization for autonomous water pumping and desalination units supplied by renewable energy sources, designed to be a viable solution to fresh water scarcity for remote areas. Non-linear gyrators as well as the non-linear efficiency of energy and flow transfers model the mechanical-hydraulic power conversion systems involved. We present a generic formulation and resolution algorithms based on piece-wise bounding and integer linear programming to solve to optimality the global optimization problem of finding an optimal energy mangement strategy.
