Abstract

The operational water management task for the navigation canal system under consideration is to maintain navigable water levels with minimum electrical energy (pump) costs. Optimal pump and discharge strategies are calculated using a process model based on the Saint Venant equations for the canal sections and predictions of the non-controllable inputs. A sequential quadratic programming (SQP) method with an interior-point algorithm for the linear-quadratic subproblems is used for solving the resulting large-scale nonlinear programming problem. The decision proposals are updated repeatedly during the day within a receding horizon or modelbased predictive control scheme.
