Abstract :
In this paper a mixed-integer hydroelectric power model for short-term planning is presented. The advantage of this model is that the schedules only include points with good efficiency. The planning problem is decomposed into a subproblem for each hydro plant. In order to get smooth schedules the model includes start-up costs for hydro aggregates. The main mathematical methods used in this work are Lagrange relaxation, dynamic programming and network programming. The model is illustrated by a numerical example from a part of the Swedish power system
