Power Event in connection to Antonio Zecchino PhD defense
Dear all,
We have the pleasure of hosting Prof. Lina Bertling Tjernberg (KTH, Sweden) and Prof. Samuele Grillo (Politecnico di Milano, Italy) as external examiners for Antonio Zecchino PhD defense.
They are willing to share their experience with two presentations about:
- On Power Grid Technologies for a sustainable energy system – with novel solutions for energy storage, electrical vehicles and smart infrastructure asset management,
- AC and DC microgrids: challenges and overview
Attached in the calendar invite you may find abstract of the presentations and biographies.
Cheers,
Mattia Marinelli

On Power Grid Technologies for a sustainable energy system
The electric power system is being modernized to enable a sustainable energy system. New developments include possibilities and challenges with generation, delivery and usage of electricity as an integrated part of the energy system. This involves new forms of usage of electricity, e.g. for transportation and demand response, and to the updating of existing electricity infrastructures. For electricity generation the trend is toward new large-scale developments, like offshore wind farms, as well as small-scale developments like rooftop solar energy. At the same time, digitalization of society is creating new opportunities for control and automation as well as new business models and energy related services. The overall trend for technology developments is new possibilities for measurement and control. An example is Phasor Measurements Units (PMUs), generally located in the transmission network, which provide measurements of voltage and current up to 30-120 times per second. Smart Meters placed with the end consumer, which enables integration of private small-scale electricity production from solar cells, or energy storage from electric vehicles and general distributed control of energy use, are others. Another trend is the development of diagnostic measurement techniques for assessing the insulation condition and prediction of lifetime of physical assets, and new methods for condition monitoring. These different trends have in common an overall development towards access to large volumes of data for handling and analysis, and another concept growing in interest are referred as Big Data, which provides new means for infrastructure asset management.
This key note presentation gives an overview of the main challenges and possibilities resulting from these developments of power grid technologies. Examples will be given on recent projects and from own research work.
Biography:
Dr. Lina Bertling Tjernberg is Professor in Power Grid Technology and the Director of Energy platform at KTH the Royal Institute of Technology, Stockholm, Sweden. Her research aims to develop models for electric power solutions for the future sustainable energy system. Areas of special expertise are in applied reliability theory and maintenance management. Dr. Bertling Tjernberg has previously been Professor at Chalmers University of Technology in Sustainable Power System and the Head of the Power System Group, and with the Swedish National Grid as Director of the Research and Development.
Dr. Bertling Tjernberg is a Senior Member of IEEE, the Chair of the Swedish PE/PEL Chapter, and is a Distinguished Lecturer of IEEE PES. She has served in the Governing Board of IEEE PES, as an Editor for the IEEE Transactions on Smart Grid Technologies, and chaired the first IEEE ISGT Europe Conference. She is an expert for the EU commission within Energy, ICT and Security. She is appointed by the Swedish Government as a member of the advisory council of the Energy Markets Inspectorate, and is a member of the National Strategic Council for Wind Power, and of the Scientific Board of the Swedish Civil Contingencies Agency. She has published over 100 papers and an author of CRC Press with a book on Infrastructure Asset Management with Power System Examples., April 2018.

AC and DC microgrids: challenges and overview
Today power systems are experiencing a revolution caused by the increase of power generators fed by renewable sources. In addition to that, this trend has been mixing with the concurrent course in power generation practice of preferring distributed and dispersed medium and small power generators instead of few localized large power plants. Beyond the great benefits that the combination of these two tendencies can achieve, there are still some significant drawbacks. Microgrids are one of the dominant solutions used in power systems to cope with the challenges of distributed generation, renewable energy sources, storage systems, etc.
This presentation will give an overview of some of the main topics on microgrids: short-circuit current increase, protection issues in dc microgrids, inertia estimation and load profile characterization.
Biography:
Samuele Grillo received the M.Sc. (Hons.) and Ph.D. degrees in electronic engineering and electrical engineering respectively from the University of Genova, Genova, Italy, in 2004 and 2008, respectively. In 2010, he was an Assistant Professor, from 2016 with a tenure track, in power systems at Politecnico di Milano. He is currently an Associate Professor at Politecnico di Milano. His research interests include smart grids, integration of distributed renewable sources, and energy storage devices in power networks, optimization, and control techniques applied to power systems. He is member of CIGRÉ WG.B5.65 “Enhancing Protection System Performance by Optimising the Response of Inverter-Based Sources”, and of the Working Group on Modern Heuristic Optimization (Analytic Methods for Power Systems Committee) of IEEE PES. He is Senior Member of IEEE and Secretary of IEEE Italy Section, Power & Energy Society Chapter.
