CODE 101702 ACADEMIC YEAR 2021/2022 CREDITS 5 cfu anno 2 INGEGNERIA ELETTRICA 8731 (LM-28) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR ING-IND/31 LANGUAGE Italian TEACHING LOCATION GENOVA SEMESTER Annual MODULES Questo insegnamento è un modulo di: NUMERICAL METHODS AND OPTIMIZATION TECHNIQUES FOR POWER ELECTRICAL ENGINEERING TEACHING MATERIALS AULAWEB OVERVIEW Module of basic numerical methods, numerical techniques for the solution of field problems, and optimization techniques for applications to the design of electromagnetic devices and systems. AIMS AND CONTENT LEARNING OUTCOMES The module describes the main algorithms used for the numerical modeling of electromagnetic devices (interpolation, root search, derivation, integration, solution of linear equation systems), describes the basis of numerical solution of field problems (described by PDE) using the Finite Element Method, and gives an introduction to the techniques for the automatic design and operational optimization of industrial devices. AIMS AND LEARNING OUTCOMES At the end of the module, the Student shall have correctly understood the basic concepts enabling him/her to correctly choose from numerical libraries the most suitable algorithm to solve the problems of interest, shall be able to correctly solve, using the Finite Element Method, problems of quasi-stationary Electromagnetic Fields, and to correctly design a numerical optimization procedure, choosing the right optimization method.

ASSESSMENT METHODS The examination of Numerical Methods and Optimization for Electromagnetic Systems is based on an oral discussion, lasting about 30 minutes, normally about the solution of practical problems, and optional questions about the related theory. The final marking of Numerical Methods and Optimization for Electrical Engineering is the average of the marks (rounded to the higher integer figure) of its modules (Numerical Methods and Optimization for Electromagnetic Systems and Optimization Techniques for Power Electric Systems).
