Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

The course deals with Energy Management Systems (EMS). It first examines the hardware and communication infrastuctures. Then, the main software functions for power system real time operation are explored. The course covers the following topics.

  • Power system control centers : functions and architecture
  • Data acquisition : SCADA system, RTUs, PMUs
  • State estimation: weighted least squares estimator, observability analysis, bad data analysis, topology errors.
  • Real-time security analysis
  • Functional optimization: economic dispatch, unit commitment, optimal power flow.

Learning outcomes of the learning unit

At the end of the course, the student will have acquired an understanding of the structure and essential functions of an Energy Management System. He will also master the computation methods dealing with power system operating point optimization, taking into account both security and economy constraints. The student will be able to master and analyse a scientific publication dealing with a general topic covered in the course. In the course project, the student will improve his/her presentation skills (including selection of relevant information, slides, spoken english) and his/her critical thinking.

Prerequisite knowledge and skills

Basic knowledge in power system components and analysis.
Basic knowledge and practice of MATLAB is also required.

Planned learning activities and teaching methods

The course comprises :

  • about 10 lectures,  in which theory and applications are covered;
  • some lectures are followed by a tutorial. Students are asked to solve illustrative exercices, some of them require the use of a power system analysis software (made available to the students) or to develop scripts in MATLAB language;
  • one presentation session at mid-term: each student is assigned a scientific  publication related to one course topic and is asked to present this research, to discuss its results and put this work in relation with the course contents.

Mode of delivery (face-to-face ; distance-learning)

Face-to-face learning

Recommended or required readings

The learning material and complementary documents will be provided by the teacher on myULiege web-site.

Assessment methods and criteria

Oral exam consisting of :

  • a critical analysis and presentation of one scientific publication dealing with one course topic, following the appoach adopted during the mid-term presentation. The assigned publication will be provided to each student during the last lecture;
  • a general question on one course topic.

Work placement(s)

Organizational remarks

The course is taught during the first quadrimester, Tuesday morning.
