Title

Roadmap towards Direct Current: How direct will the future electricity be?

Guest lecturer

Professor Pavol Bauer,  Delft University of Technology, the Netherlands

Time

10:30 - 11:15

abstract

Increasing number of decentralised energy resources and loads that operate with direct current, such as photovoltaic cells, fuel cells, batteries and electric vehicles, result in dc microgrids having the potential to provide more advantages than ac microgrids in certain applications. DC microgrids (both grid connected and stand- alone) can provide higher flexibility by allowing the controlled injection of locally generated electrical energy and by enabling the optimisation of energy storage, leading to a better deployment of resources. Integration of renewable energy sources namely solar cells and storage (Electric Vehicles) is addressed in the presentation. Several examples of integration of dc microgrids and needed power electronic interfaces and systems with high efficiency will be shown. DC microgrids have potential to grow into a dc distribution grids in a modular way. Roadmap towards the dc distribution grids will be presented and challenges listed and explained. HV/MV DC Transmission Networks for large scale implementation of Renewable Energy Sources (solar, wind, wave), optimization and controllability of HVDC transmission grids is addressed too.

About the lecturer

Pavol Bauer is currently a full Professor with the Department of Electrical Sustainable Energy of Delft University of Technology and head of DC Systems, Energy Conversion and Storage group. He published over 80 journals and almost 300 conference papers in his field, he is an author or co-author of 8 books, holds 5 international patents and organized several tutorials at the international conferences. He has worked on many projects for industry concerning wind, solar and wave energy, power electronic applications for power systems such as Smarttrafo; HVDC systems, DC distribution grids and microgrids, projects for smart cities such as PV charging of electric vehicles, PV and storage integration, contactless charging; and he participated in several Leonardo da Vinci and H2020 EU projects as project partner (ELINA, INETELE, E-Pragmatic) and coordinator (PEMCWebLab.com-Edipe, SustEner, Eranet DCMICRO).

Title

How to Model a DC Microgrid. Towards an Automated Solution

Guest Lecturer

Professor Javier Uceda Antolín, Electrical and Electronic Engineering Department at UPM, Spain

time

11:15 - 12:00

abstract

DC microgrids are envisioned to be Electronic Power Distribution System composed of COTS (Commercial Off-The-Self) converters. Naturally these converters will determine the dynamic behavior of the system. Besides, unlike classic Power Electronics Systems, microgrids are highly variable due to the intermitent behavior of the renewable sources and customer consumption. In this context there is not an accepted solution to create a model able to account for the large-signal dynamic behavior of the converters, their different operating modes or the interaction among them, which could lead the dynamic degradation or even instability. This work proposes black-box polytopic model using dynamic weighting functions. This modeling strategy is one step forward towards the complex task of defining an automated tool able to model the phenomena arise in DC microgrids.

About the lecturer

Javier Uceda obtained the M.Sc. and Ph.D. degrees in Electrical Engineering by the Universidad Politécnica de Madrid, Spain in 1976 and 1979 respectively. He is currently Full Professor in Electronics in the Electrical and Electronic Engineering Department at UPM. His research activity has been developed in the field of Power Electronics where he has participated in numerous national and international research projects. His main contributions are in the field of switched–mode power supplies and dc/dc power converters for telecom and aerospace applications. More recently, Prof. Uceda´s research interest has been focused in modeling and stability analysis in AC and DC microgrids. As a result of this activity Prof. Uceda has published more than three hundred papers in international journals and conferences and he holds several national and international patents.

He has been member of the Editorial Board of the European Power Electronics and Drives Journal and he has been Associated Editor of IEEE Transactions on Industrial Electronics. He is also senior member of the Administrative Committee of IEEE Industrial Electronics Society, where he was Vice-President of Technical Activities in 1991. He belongs to the International Steering Committee of the European Power Electronics and Drives Association where he was Vice-President. Prof. Uceda is also member of the Scientific Advisory Board of the Center for Power Electronics Systems (CPES) in USA. In December, 2004 he was awarded as an IEEE Fellow.

The guest lectures will take place in pon 105, room 3.115, and all are welcome.
