	Teaching Methods
	The course includes classroom lectures (about 60%), classroom and laboratory exercises (about 40%). During lectures, the instructor interacts with all students keeping them involved in the development of theory, checking their comprehension. During classroom exercises, examples of the theory and methods are discussed. The students are invited to solve assigned exercises under the guidance of the lecturer. In laboratory practice, student will make experimental tests on scaled prototypes and/or with grid emulators suitable to reproduce the behavior of large real power systems. Frontal lessons are provided. English is the official language.

	Verification of learning
	The final exam is aimed at evaluating: the knowledge and understanding of the concepts presented during the course, the ability to apply that knowledge to solve problems of analysis of electric power systems, the ability of making judgement, the communication skills and the learning abilities. The final exam consists of a practical test and an oral interview. The practical test includes circuital analysis of electrical distribution networks, also assisted by computational and simulation software. Selection and sizing of power system components, load flow analysis. Study of electrical networks under fault conditions The exercises can be formalized as a pre-evaluated test developed through the university e-learning platform. Examples of practical tests will be shared through the webpage of the course. The scope of the written test is to assess the ability to apply the acquired knowledge, the ability to formalize and solve a problem, the ability of making judgment. The written test will be evaluated based on the correctness of the approach and results. For the practical test the following scale will be adopted: a=excellent, b=good, c=fair, d=acceptable +, e=acceptable; f=fail. A minimum mark of e=acceptable is needed to access the oral test. The oral interview is aimed to assess the ability and the quality of oral exposition, the ability to defend and critically discuss the actions and choices proposed in the practical test, and will also deal with all the topics presented during the course. The evaluation takes into account the knowledge demonstrated by the student, the learning skills, the quality of the exposition, the quality of the presented report. The final result is marked out of thirties. Marks=18 is given to students demonstrating very limited but sufficient knowledge and application skills. Marks=30 can be given to students showing a complete knowledge of methods, techniques and concepts presented, link them one another, demonstrating a very effective approach to problem solving and able to find accurate solutions. Honors (30 e lode) can be given to students demonstrating they can apply the acquired knowledge with considerable autonomy and critical judgment.
