2021 CIGRE Virtual Centennial Session

mercoledì, 18.08.2021, 09:40 - venerdì, 27.08.2021, 16:00 CEST

The 2021 CIGRE Virtual Centennial Session is complementary to the signature event in Paris which was held in August 2020, and the next event will be held in August 2022.

This unprecedented online event will offer a vast wealth of power system expertise, digitally shared from across the global CIGRE community, and Hitachi Energy plays an active role in Group Discussion Meetings, tutorials and workshops. 

Our contributions cover numerous subjects in areas such as Transformers, High Voltage Equipment and new materials, substations, HVDC, Power Electronics and hydrogen as well as Active distribution systems and environmental aspects. We also present new methods and algorithms for system expansion planning and operation in transmission systems and in active distribution systems, and visionary concepts of smarter, stronger and greener future power systems. 

Our experts participate in Group Discussion Meetings, tutorials and workshops, and in study committee management meetings all over the week. Meet some of our experts here.
