Learning objectives
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).

Teaching methods
Classroom lectures, featuring exercises and numerical examples solved by the instructor.The course typically features also 2-3 seminars on advanced topics given by expert instructors and professionals.
Assessment methods and criteria
Oral 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).
