2020 Oct – Network meeting, Barcelona

Due to the pandemic situation, the Cinergia & UPC network meeting in Barcelona took place virtually. Nonetheless, InnoDC’s Barcelona-based researchers, Luis, Jovana, Saman and Daniel helped organise a busy week’s training. All the researchers took part in the following.

Offshore & Floating Wind Europe digital conference & exhibition, Reuters.

KU Leuven:
Click on the titles to read Jef Beerten’s presentation Covid-19 Impact on the Power System and Hakan Ergun’s What can we learn from the Covid-19 pandemic for the renewable energy transition? And read the report Sharing Knowledge on Electrical Energy Industry’s First Response to Covid-19.

Red Eléctrica de Espaňa:
Luis Coronado presented the experience of the project INELFE, the 2 x 1000 MW VSC-HVDC interconnection between France and Spain, then answered questions on the future needs and challenges for the HVDC industry.

IREC Catalonia Institute for Energy Research:
José Luis Dominguez-Garcia (Head of Power Systems) delivered the workshops How to Work Remotely and Web-based Collaborative Tools.

InnoDC lecture to MSc students:
Click on the title to read about their lecture: Grid Integration of Renewables.

Cinergia day:
Daniel Westerman Spier explained ‘MMC (modular multilevel converter) modelling and applications’ and his role at Cinergia.
Gabriel Gross, R&D Senior Engineer, described two projects developing and fabricating MMCs at Lille (France) – the 2nd project evolving from the 1st, moving from half-bridge converter to full bridge.
Miquel Teixido, Director & Sales Manager, shared his experience from engineer to company director and how Cinergia had developed since 2008. He then took us on a virtual tour of the premises. Watch the video!

Committee meeting:
Jovana Dakic presented a report, outlining how the researchers had adapted to Covid-related disruptions, and suggested solutions, such as data exchanges in place of on-site secondments.

Work package updates:
Daniel Westerman Spier, Emily Maggioli and Anubhav Jain chaired a three-hour session based on research update videos. This involved strict time-management, co-ordinating questions & answers and monitoring the chat column. See below for the presentation topics.
