Modelling and optimization of energy systems

Summary

The goal of the lecture is to present and apply techniques for the modelling and the thermo-economic optimisation of industrial process and energy systems. The lecture covers the problem statement, the solving methods for the simulation and the single and multi-objective optimisation problems.

• Model , design and optimize energy conversion systems and industrial processes, E22

Transversal skills

• Write a scientific or technical report.
• Make an oral presentation.
• Keep appropriate documentation for group meetings.
• Access and evaluate appropriate sources of information.

Teaching methods

The course is organised as theoretical sessions and the resolution of a real case study to be realised by a student team coached by an assistant.

Expected student activities

Participation to a team project and contribution to the report.

Active participation to the lectures and mastering the theoretical concepts applied to solve the project.

Assessment methods

-Quizz during the lecture sessions

- Group project

- An oral exam will concern the theory and its application in the case study.

Supervision
