Objetivos

This course is intended to provide the Electrical Engineer of Renewable Energies and Power Systems with knowledge related to the problems associated with optimal dispatch (OD), as well as knowledge of reliability in generation systems. So, with respect to the DO. As objectives, it is intended that the student learns concepts such as: The operation of the SEE must be conducted in order to optimize the production cost and guarantee the security of supply. Understand the classic DO problem, which consists of determining the power to be supplied by each generator in service. Apprehend the concept of global minimum cost.
Production capacity planning. The installed capacity equal to the expected peak (maximum power) plus a fixed percentage of the peak. Apprehend the concept of Operating Capacity, as well, that operating capacity equal to the maximum demand plus a reserve equal to one of the largest units in operation, among others.

Métodos de ensino e atividades de aprendizagem

Theoretical-practical classes will have a component based on the exposition of the syllabus of the discipline and another component based on the exemplification, in terms of applications, of that content, and on problem solving.
This exhibition will be complemented with laboratory work by the student, where a strong component of autonomous work is privileged over the development of the proposed works.
