Learning outcomes of the course unit

1) Knowledge and understanding

Attending classes and through individual study, students are to acquire basic knowledge of:

- basic concepts and problems of the generation, transmission and distribution of electricity in power systems
- power, frequency and voltage control techniques

2) Applying knowledge and understanding

- A goal of this course is providing students with the ability of applying their knowledge of power electronics, energetics and controls to power systems
- importance is also given to the ability of solving quantitative problems and exercises.

Prerequisites

Students should be familiar with the notions of mathematics, physics, electrical engineering and power electronics typically acquired in first-level degrees in Information engineering (class L-8). For the University of Parma graduates in "Ingegneria informatica, elettronica e delle telecomunicazioni" important preliminary notions can be found in the course of "Generazione e conversione da fonti rinnovabili". The part on semiconductor power switches relies on the topics treated in the course of "Dispositivi a semiconduttore".

Teaching methods

Classroom lectures, featuring exercises and numerical examples solved by the instructor.
For the academic year 2020/21 the course will be taught on-line, with streaming on the Teams platform, and recorded lectures available (at least for 3 days) on the Elly platform.

Assessment methods and criteria

Oral exam. The exams will be held in the classroom and/or on-line depending on the regulations and indications in place at the time of the exam.

Students will have to show good understanding of the theoretical aspects treated in the lectures, and the ability to solve simple quantitative exercises by hand calculations.

The student is typically required to answer to two questions, one on the topics of part 1 (1-5), one on those of part 2 (6-12).

Students can choose to speak either Italian or English at the exam. Students who are not native English speakers and show sufficient fluency with technical English are awarded up to 2 extra points (out of 30).
