Smart grids

This course is aimed at giving students with an ICT background a view on the structure and operation of modern and future electrical networks (smart grids), also pointing out the aspects referring to the interaction between power and energy systems and ICT contents. Starting from an overview on the evolution of the power and energy systems towards the construction of supergrids in high voltage bulk transmission systems and of microgrids in electrical distribution systems, the course addresses in a specific way the topics referring to the structure and operation of Medium Voltage and Low Voltage distribution systems, highlighting the contributions of the ICT sector to network modernization with increasing levels of automation, control, communication and data management. At the end of the semester, the student will have to gain knowledge on a set of aspects that enable him/her to dialogue with the operators of the electrical distribution system by using appropriate terminology and showing adequate competence in discussing about basic network-related problems. In addition, the student will have to gain competence in formulating optimization problems referring to the electrical distribution networks, choosing the most suitable methods to solve these problems. Finally, the student will be able to interact in an effective way with the network operators to discuss about the application of ICT solutions to the smart grid.
