Introduction and Objectives

The project aims for two new features: 1) the simultaneous consideration of bidding power in the liberalized market and 2) bilateral contracts (between a generation company and a consumer client). These features take into consideration the future elimination of current regulations wich discourage bilateral contracts and entail the development of optimization procedures that are more efficient than those now employed to solve these problems. This higher efficiency will allow a more accurate modeling and solve larger, real problems in reasonable CPU time. In this project, both modeling languages and commercially available solvers are employed on the one hand, and our own optimization algorithms on the other. The algorithms that are being developed include the use of: interior-point methods, global optimization, column-generation methods, and Lagrangian relaxation procedures which employ dual methods
