Power Electronics for a Smart Energy Management: from Smart Transformer to 100 % Electronic Grid by means of Grid-Forming and Talkative Power Conversion Technologies
Abstract: The goal to decarbonise the energy production and use especially in the transportation sector is challenging the modern power system. Power electronics is now playing a different role respect to 20 years ago, taking directly responsibility for the electric grid, eventually evolving towards an electronic grid. Power converters will play a grid-forming role being not only in charge of adjusting voltage level and create different AC and DC supply but also to control generation, loads and power flow among them. The Smart Transformer, which is a fundamental node of the future electronic grid, is now in the process to be standardized as for IEEE and CIGRE initiatives. On the other hand the energy management functionality of power-electronic-based devices as the Smart Transformer needs communication to get information from sensors and send command to actuators and better manage the future dynamical reconfigurable meshed and hybrid grid and its protection. Power electronic can also provide communication functionalities embedding data directly in the Pulse Width Modulation also thanks to Wide Band Gap devices which allows higher switching frequency still with limited losses. This will open a new era for networked systems experiencing hyper-connectivity at different levels but still using the same device, the power electronics converter, where the conversion architecture and the Pulse Width Modulation are now re-thinked in a new and exciting perspective bridging two different realms of knowledge: power conversion and communication.
Bio: Marco Liserre (S’00-M’02-SM’07-F’13) obtained the MSc and PhD degrees in Electrical Engineering from the Politecnico di Bari in 1998 and 2002 respectively. He has been Associate Professor at the Politecnico di Bari and, since 2012, Professor of Reliable Power Electronics at Aalborg University (Denmark). Since 2013 he is Full Professor and holds the Chair of Power Electronics at the University of Kiel (Germany). He has been offered and declined professorships at several universities. He has published more than 700 technical papers (1/3 of them in international refereed journals), one book and 5 granted patents. These works have received more than 50,000 citations. Marco Liserre is listed in the 2014 ISI Thomson report “The world’s most influential scientific minds”. Several of his students (MSc, PhD and post-docs) are in leading positions in industry and universities worldwide. In 2023, he joined the Fraunhofer ISIT on a part-time basis as deputy director and director of the new division “Electronic Energy Systems”, as well as the Kiel branch of the Fraunhofer ISIT.
He is a member of IAS, PELS, PES and IES. He has served all these societies in various capacities. In PELS, he is Co-Editor of the IEEE Open Access Journal in Power Electronics and Technical Committee Chairman of the Committee on Electronic Power Grid Systems. He has co-chaired several IEEE conferences. He has received 15 awards from IEEE, PCIM and EPE-PEMC, including the prestigious 2018 IEEE-IES Mittelmann Achievement Award and the 2023 IEEE-PELS R. David Middlebrook Achievement Award. In 2023, he was awarded the title of “Ufficiale” by the President of the Italian Republic.
