Contenu

Electrical energy networks currently appear to be central elements of the energy transition. They are the seat of major technological challenges resulting from developments and evolutions such as the growing electrification of some energy uses (mobility, heating systems, industrial processes and systems...), the massive integration of renewable energy sources, electrical storage, etc. These challenges affect the planning, operation and management of these complex systems, which are at the heart of the content of this course.
Major addressed topics:

• Electricity as energy carrier, architecture and constitution of power systems,
• Power systems physical concepts and modelling: transmission and distribution links (power transformers, lines, cables), generators and sources (synchronous machines, renewable energy conversion systems), power electronics devices used for grid control and operation (HVDC links, Flexible AC Transmission Systems),
• Load-Flow calculation,
• Electrical power systems planning concepts,
• Optimal and secure operation of power systems (Optimal Power Flow, units commitment and economic dispatch problems, contingency analysis),
• Frequency and power control,
• Voltage control,
• State-estimation,
• Balanced faulty operation (short circuit), basic introduction to power grids protections.

Méthodes d'enseignement

• Lectures
• Practical sessions (supervised exercise sessions).
• Project to be carried out by groups of two students, based on the use of dedicated software for power systems design and analysis (This project is evaluated and taken into account in the final evaluation grade.)

Technical visit (e.g. training centre ELIA, Belgian transmission high voltage grid operator, and the national dispatching.)

Modes d'évaluation
des acquis des étudiants

Students will be assessed:
- Based on a project carried out in groups of two during the semester;
- Individually on the basis of a written or oral examination relating to the content of lectures and practice sessions
To constitute the final mark, the weighting given to the project is:
- 33% if the mark of the individual exam is higher than 10/20;
- 0% if the mark of the individual exam is less than 8/20;
- linearly progressive between 0%, if the individual exam mark is 8/20, and 33%, if the exam mark is 10/20
The project cannot be redone; the mark is acquired in the first quadrimester and kept in the event of a second session.
Note: The use of generative AI software such as chatGPT is permitted only for assistance in writing of the reports requested in this course. In this instance, however, an appendix will be required detailing, for each of the sections concerned, how the AI was used (information search, drafting and/or correction of the text, ...). Furthermore, external sources of information must be systematically cited in compliance with bibliographic referencing standards.

Autres infos

An optional test is organized in the middle of the semester. Successful completion of this test might result in a bonus point for the final mark (details on moodle)
