Smart Grids / Power Systems


at the end of the course, it is expected that students acquire knowledge and competences that allow them to:

- understand the working principle of power systems, focusing on power flow ans short circuit analysis

- identify and understand the role of the different actors in the electric power value chain

- know and critically analyse the ongoing energy transition, its inherent challenges as well as understand the concept of flexibility and its sources and aplications in power systems.

Teaching method

The different concepts are explained by the lecturer using adequated multimedia material and using real power systems examples as much as possible

The students will solve problems shared in the course materials in a semiautonomous way. oral communication are incentivized.

The students have contact with a industry grade power system simulation software, used by multiple system operators at European level.

Evaluation method

The evaluation in this course follows one of two options:


Option A - 3 Minitests (MT1, MT2 e MT3) + 1 Project work (TL)

Theoretical Component (CT) = (0,1667*MT1 + 0,50*MT2 + 0,3333*MT3) >= 9,5 val.

     MT3 grade >= 7 val.

Laboratorial Component (CL) = 1*TL >= 9,5 val.

Final Grade = 0,60*CT + 0,40*CL >= 9,5 val.


Option B - 1 Final Exam (EF) + 1 Project work (TL)

Theoretical Component (CT) = l*EF  >= 9,5 val.

Laboratorial Component (CL) = 1*TL >= 9,5 val.

Final Grade = 0,60*CT + 0,40*CL >= 9,5 val.


In both options, studens will be approved in the course only if their final grade and also the grades in each one of the two components (CT and CL) is equal or higher than 9,5 values (scale from 0 to 20).

The grade of the laboratorial component (CL) may be subjected to oral discussion with the lecturer.
