Moodle

> https://moodleucl.uclouvain.be/course/view.php?id=5473

• Dynamic modelling, control and analysis of transient behaviour of power systems, especially in the significant presence of power generation units from renewable sources (wind, photovoltaic, marine and others)
• Applications of power electronics to the management of electrical energy and power grids, in particular (transmission networks: Flexible AC Transmission Systems (FACTS), DC link (HVDC); distribution networks (D-FACTS, active filters))
• Smart Grids: active demand management, energy storage, management of the massive integration of distributed generation in distribution networks, evolution of the concept of ancillary services, micro-grids, power systems monitoring and automation.

In view of the LO reference frame 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

- AA3.1, AA3.3

- AA5.6

- AA6.1

Specifically, at the end of the course, students will be able to:

• Model electrical power systems and study their dynamic behaviour, especially with the help of specialized software tools,
• Explain electrical features and dynamic models of electricity generating units from renewable sources,
• Explain the characteristics, features and models of power electronic systems used to manage the transmission and distribution of electricity,
• Understand the technical challenges for electric power systems, anticipating and resolving issues related to the increasing electrical power generation from renewable energy sources.

Transversal learning outcomes:

• Use of specialized software tools
• Address the question of the changing energy landscape, particularly the role of renewable energies and the new challenges linked to them (to be taken up by the various actors in the power systems)

Students are assessed during an oral examination, for which they can have the courses and their personal notes supports.

The examination mark accounts for 50% of the final grade.

The marks of small projects made during the semester account for 50% of the final grade.

• Lectures for the introduction of the basic theoretical concepts and general context description
• Exercises (projects): solving particular problems with the help of dedicated software tools. Discussion forum, practical issues concerning the use of software tools and results. Consulting sessions (coaching).

• Generalities, a reminder of basic concepts of electricity networks
• Dynamic modelling of systems:

1. Synchronous machines (Park's model, simplified models, characteristic parameters),
2. Wind turbine generators (cage induction motors, doubly-fed induction machines, permanent magnet synchronous machines and associated power electronic converters),
3. Photovoltaic systems,
4. Power electronics converters used in the technical management and operation of energy networks: HVDC links, FACTS,
5. Other network components and loads,
6. Energy Storage Systems.

• Introduction to the concepts of stability
• Introduction and use of specialized software tools for the analysis of the dynamic behaviour of electrical systems
• Smart Grids: current issues (technical management of networks (congestion, stability, voltage control ...), ancillary services, the role of energy storage etc.)
