    TEACHING MATERIALS AULAWEB

    OVERVIEW

    The course provides the main methods to study a traditional and a state-of-the art power system both at steady state and in transient. Particular interest is devoted to the integration of renewables and to the control and management of microgrids.

    AIMS AND CONTENT

    LEARNING OUTCOMES

    The course is designed to provide the theoretical and methodological skills necessary for the understanding of the most important problems of modern electrical power systems, with particular reference to the integration of renewable energy sources (RES) and the impact that the change in the characteristics of the generating units determines in the electrical network management. The course, with strong interactive features, is proposed to support theoretical lectures with a large "experiential" part in which, through the use of dedicated software, the student can apply personally what learnt during the theoretical explanations.

    AIMS AND LEARNING OUTCOMES

    The main aim of the course is to have students not having a powerful background in electric power systems to go through the main issues related with steady-state and transient characteristics of the electric network in order to connect them with the concepts learnt in other subjects related to energy engineering.

    The main expectation is not to learn a lot of concepts, but to be able to think, formulate hypotheses and infer consequences and conclusions

    TEACHING METHODS

    Theroretical lectures and exercises with dedicated software

    SYLLABUS/CONTENT

    The structure of the overall power electric system (transmission networks, distribution networks, utilization)
    Overview of the main traditional components of the electrical system (generators, transformers, motors, transmission lines, breakers, surge arresters)
    Analysis of steady-state power systems: the Load Flow problem
    The transient stability problem.
    Traditional power system regulations: the frequency/active power regulation and the reactive power/voltage control
    Integration of renewable energy sources to the electricity grid (photovoltaic and wind) with particular reference to the analysis of standards and grid codes.
    Development of simple control algorithms for the optimized management of smart grids.

    Control of islanded microgrids

    EXAMS

    EXAM DESCRIPTION

    Oral examination after delivery of the report on the exercises done during the semester.

     

    - For students with specific learning disabilities, more time will be
    available and the use of concept maps will be allowed, after presenting
    the relevant certificate.

    - Students with learning disorders ("Disturbi Specifici di
    Apprendimento", DSA) will be allowed to use specific modalities and
    supports that will be determined on a case-by-case basis in agreement
    with the delegate of the Engineering courses in the Committee for the
    Inclusion of Students with Disabilities

    ASSESSMENT METHODS

    A written question on a general topic in order to check the ability of the student to organize his time and the flowchart of an answer. A second oral question on a realistic  case is proposed in order to check the ability of the student of thinking about real problems
