Research Profile

Power electronics is a key technology to enable the transition towards a decarbonized society. However, the development of a reliable and affordable power system dominated by power electronics poses numerous challenges regarding its design, operation, control and protection that need to be addressed.

My research activities focus on providing solutions to some of these challenges through:

1. the development of mathematical tools and models to assess the stability of power systems dominated by power electronics,
2. the identification of interactions and interoperability issues between electrically adjacent converters and other devices and components,

• the modelling and simulation of different power converter topologies and

1. the development of modulation strategies and control algorithms, with emphasis in grid-following/supporting/forming techniques, for power electronics interfaced distributed energy resources (DERS) in ac, dc and hybrid ac/dc grids.

These research lines are developed building on a theoretical approach combined with advanced experimental validation by means of control and power hardware in the loop tools.

I also participate as technical coordinator and researcher in projects with the private sector, academic institutions and research bodies interested in these topics.

Academic background

Salvador Ceballos received the M.S. degree in Physics from the University of Cantabria, Santander, Spain, in 2001, and the M.S. and Ph.D. degrees in electronic engineering from the University of the Basque Country, Bilbao, Spain, in 2002 and 2008, respectively. Since 2002 he has been with Tecnalia Research and Innovation, where he is a principal researcher with the Energy, Climate and Urban Transition Unit. He has participated in multiple projects with focus on the modelling, simulation, modulation and control of power electronics for DERs and HVDC (VSC-HVDC) transmission systems. In the last years, he has been involved in projects to model and assess the stability of converter-dominated power systems.

Salvador has been an Invited Visiting Researcher with the HMRC (Hydraulic and Maritime Research Centre) University College Cork (UCC), Ireland, with the Australian Energy Research Institute, UNSW, Sydney, Australia and with SINTEF Energy, Trondheim, Norway. He has also been with the Energy Research Institute (ERI@n), NTU, Singapore in double affiliation with Tecnalia.
