AIMS AND CONTENT

LEARNING OUTCOMES

Introduction to static problems related to the operation, design and planning of electric power systems represented by mathematical or circuit models. Preliminary analysis of dynamic models and transients of power systems that include the technologies for the energy transition.

AIMS AND LEARNING OUTCOMES

To solve problems of analysis of the operation of an electric power system, in particular for load flows at steady-state and for quantification of the effects of harmonic phenomena, using both dimensional and in "per unit" values.

To study and characterize modelling and implementation solutions for the transfer of electricity, considering conventional and renewable distributed generation resources and use for civil, industrial and mobility purposes.

To develop illustrative reports of case studies concerning steady-state and harmonic analyses of simple electrical infrastructures.

TEACHING METHODS

Theoretical and practical lectures (5 hours per week), including examples of solving written exams.

Collaborative lectures for the drafting of calculation reports on the assigned case studies.

Students having disabilities or Specific Learning Disorders can request suitable aids for the examinations. Such aids will be defined according to specific needs, together with the Referent for the Polytechnic School of the Committe for the inclusion of Students with Disabilites and with SLD. Students in such conditions are invited to get in touch (via e-mail) with the Teacher a sufficient time before the examination, inserting in copy the Referent for the Polytechninc School (https://unige.it/en/commissioni/comitatoperlinclusionedeglistudenticondisabilita.html), without sending any document about their disabilites.

EXAMS

EXAM DESCRIPTION

The learning assessment includes a written test (lasting 2 hours), consisting of the resolution of numerical exercises on the topics specified in the specific learning objectives. The admission assessment allows students to take the oral exam, which lasts about 1 hour.

Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Federico Scarpa (federico.scarpa@unige.it ), the School's disability liaison.

ASSESSMENT METHODS

Verification of the acquisition of theoretical and practical knowledge of the calculation methodologies typically used for the operational management of electric power systems. The written exam will assess the student's ability to solve numerical exercises. The oral exam will verify the student's ability to re-propose and argue on theoretical and applicative methods concerning the steady-state and harmonic analysis of electrical power systems. The quality of the exposition and the correct use of specialized vocabulary, the ability and autonomy of reasoning, the correct use of units of measurement and the recall of previously defined cultural prerequisites will also be evaluated.
