Summary:
The transition to a net-zero energy system requires a massive change in how electricity is produced, transported and used; the power electronic converters are the core of this paradigm-shifting, and the control techniques used on them primarily influence the power system’s dynamic behaviour. It is well documented that the power of electronic converter-based resources has created new challenges from the protection system perspective. One of the challenges from the protection point of view is coming from the signature of the output current of inverter-based resource (IBR) during short circuit conditions. It differs from traditional rotational electrical machines during a short circuit. The semiconductor switching devices of the power electronic converter are intolerant to overcurrents, so the short circuit current contribution is limited to avoid damage to the switching devices, and during this limited operation, the output waveform can be nonsinusoidal.
Bio: Francisco M. Gonzalez-Longatt is currently an academic in Electrical Power Systems at the Centre for Renewable Energy Systems Technology (CREST) at Loughborough University and an invited full professor in electrical power engineering at Institutt for elektro, IT og kybernetikk, Universitetet i Sørøst-Norge, Norway. Founder and leader of the DIgEnSys-Lab = Digital Energy Systems Laboratory and a global research initiative for digital energy systems.

His academic qualifications include first Class Electrical Engineering from Instituto Universitario Politécnico de la Fuerza Armada Nacional, Venezuela (1994), Master of Business Administration (Honors) from Universidad Bicentenaria de Aragua, Venezuela (1999), PhD in Electrical Power Engineering from the Universidad Central de Venezuela (2008) and Postgraduate Certificate in Higher Education Professional Practice from Coventry University (2013) and Diploma in Leadership and Management (ILM Level 3), Loughborough University (2018).

He is a former Lecturer in Electrical Power Systems at Wolfson School of Mechanical, Electrical and Manufacturing Engineering and a member of the Centre for Renewable Energy Systems Technology (CREST) at Loughborough University, UK. He is a former academic staff of the Department of Aerospace, Electrical and Electronic Engineering at Coventry University, where he started as a Lecturer in Electrical Engineering in 2012 and was promoted to Senior Lecturer in Electrical Engineering in 2013. He was formerly with the School of Electrical and Electronic Engineering, The University of Manchester as a Postdoctoral Research Associate (2009-2011). He is a former associate professor (1995-2009) and Chair (1999-2001) of the Department of Electrical Engineering of Universidad Nacional Politécnico de la Fuerza Armada Nacional, Venezuela (1995-2009).
