Abstract |
|
|
| In this work we analyze an optimal control problem for a system of two hydroelectric power stations in cascade with
reversible turbines. The objective is to optimize the profit of power production while respecting the system’s restrictions. Some of these
restrictions translate into state constraints and the cost function is nonconvex. This increases the complexity of the optimal control
problem. The problem is solved numerically and two different approaches are adopted. These approaches focus on global optimization
techniques (Chen-Burer algorithm) and on a projection estimation refinement method (PERmethod). PERmethod is used as a technique
to reduce the dimension of the problem. Results and execution time of the two procedures are compared. |
