1 Contribution of the course to the program objectives
In view of the LO frame of reference of the "Master Electrical Engineering", this course contributes to the development, acquisition and evaluation of the following learning outcomes:
- AA1.1, AA1.2, AA1.3
- AA2.1, AA2.2
- AA3.3
- AA6.1
Specific LO of the course
  • Remember the main orders of magnitude and units in the field of electrical energy systems and more specifically power grids assets,
  • Understand the main technical features, functionalities and operating modes of public electricity transmission and distribution networks as well as industrial electricity distribution networks,
  • Understand technological specificities and apply relevant theoretical principles to model the main components of power systems (power transformers, lines, cables, sources, loads, FACTS) and solve general problems of load-flow calculation,
  • Use the previous competences in order to investigate and analyse practical situations, and solve technical problems regarding planning and operation of power systems in steady-state (including voltage control, frequency and power control, grid optimal and secure operation)
  • Understand the main principles of electric power systems economics
 
Content
  • 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.
Teaching methods
  • 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.)
Evaluation methods
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.
Other information
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)
