In this study the authors present the weekly optimization of a power system consisting of hydro and thermal units. The mathematical model, a mixed integer (linear) programming problem, is discussed and the solution of the unit commitment and economic dispatch problem is determined over a period of a week on an hourly basis. The system contains 840 integer variables and 1344 continuous variables, with a sparsity of 0.11%. This work allows both the water in the hydro unit and in the pump-storage unit to be costed.
