Learning Goals
The general objective is to understand and study the functional structure of the electricity sector in the Iberian context, analyzing, in particular, the advanced methods and techniques relating to the problem associated with the real-time operation of the power systems (PS) and their economic interpretation ( EI). It is also intended to develop research competencies using computational methods (CM) for simulation based on the GAMS programming language. At the end of the course unit students should be able to apply the techniques studied in real contexts.

Teaching Methods
The evaluation centered on the results of continuous learning will allow an adequate valuation of the work developed by each student. The final assessment shall be weighted as follows:
Homework: 25%
Seminars: 15%
Projects: 35%
Oral exam: 25%
To obtain approval, the student can not have in the oral exam a mark lower than ten values.
