Dr Jacques Maritz, a lecturer at the UFS Department of Engineering Sciences (EnSci), recently hosted and chaired a mini-symposium on the role of UFS Grid Related Research.

During 2020 the University of the Free State (UFS) Qwaqwa campus experienced a loss of electricity supply for 10% of the year which led to emergency generation costs reaching R1.2-million. 

This is one of the problems Dr Jacques Maritz, a lecturer at the UFS Department of Engineering Sciences (EnSci), and the UFS Grid Related Research group are looking to address with their research on green and sustainable digital transformation efforts of local campus power grids.

Dr Maritz recently hosted and chaired a mini-symposium on the role of UFS Grid Related Research during which research strategies, visions and missions were shared by different research groups. These groups included the UFS Grid Related Research Group (presented by Dr Maritz), the UFS Initiative for Digital Futures (presented by Mr Herkulaas Combrink and Prof Katinka de Wet, both interim directors) and the Block Chain Research Group (presented by Mr Riaan Bezuidenhout, a PhD student at the Department of Computer Science and Informatics).  

Dr More Manda, on behalf of merSETA strategy and research, presented its strategic priorities for the next couple of years, which included the observation to drive the development of Digital and Green Skills. Mr Nicolaas Esterhuysen, from UFS Department of University Estates, also presented a live demonstration of the current state of the UFS smart grid. Industry partners presented a synopsis of their efforts and products pertaining to the evolution of digital and green campus grids. 

The symposium highlighted the existing synergies and visions

The symposium boasted an international keynote by Dr Veselin Skendzic (locally supported by Mr Deon Joubert, SEL), a principal research engineer with Schweitzer Engineering Laboratories  Inc (SEL), on the detection of power grid faults using the phenomena of travelling waves.

“The symposium highlighted the existing synergies and visions shared between UFS research groups, our industry partners and funders. An innovative model of industry engagement via shared case studies and technical papers, with emphasis on local campus grids, was explored and discussed. 

“The UFS Initiative for Digital Futures placed emphasis on the value-add of multidisciplinary research teams when attempting to solve the most critical social problems, especially in the South African digital paradigm. One of the notable successes of this symposium was that it provided a platform for several research groups within the paradigms of science, engineering and social sciences to synchronise with industry and showcase their expertise towards the effort of creating green and sustainable campus grids,” says Dr Martiz.

According to him, the critical discussions observed during the symposium aim towards future efforts that include working more closely with industry partners and leveraging internal collaborations in order to advance the digitalisation, optimisation, reliability and research-readiness associated with campus grids. The latter is also part of the mandate of the UFS Grid Related Research Group to build local research instruments that will serve a wider community of scientist and engineers. 

Additional benefit

An additional benefit of a fully digitally twinned campus grid is the value-add of the corresponding data lake, an entity that will serve the establishment of new frontiers in digital R&D exchanges, governed by the appropriate digital ethics, says Dr Maritz.

He continues: “The UFS is in a unique position to compete in the Digital Futures paradigm, with emphasis on its ability to generate innovative digital backbones to serve multidisciplinary research interactions between internal research groups and industry, with unique contributions generated in the field of digital training. The UFS Grid Related Research Group has also been receiving valuable support, training, and guidance from the Emerging Scholars Accelerator Programme (ESAP), led by Dr Henriëtte Van Den Berg, including mentorship by Prof Pieter Meintjes, senior professor at the Department of Physics, UFS. 

“This symposium was part of the engagement efforts by the UFS Grid Related Research Group as the main driver of the merSETA funded UFS project for Digital and Data Engineering, which is closely affiliated with the initiative for Digital Futures.”

Inspiration from an Olympic Champion for Spring graduandi

The guest list for the Spring Graduation ceremony of the University of the Free State included an Olympic gold medallist, a former Miss South Africa finalist and the Prime Minister of a neigbouring country.

The new graduates could draw inspiration from Olympic swimming champion Chad le Clos, who was the guest speaker at the event. Also attending was the Prime Minister of Lesotho, the Honourable Thomas Thabane, who came to watch his grandson graduating from Kovsies. Sharing a stage with Le Clos was Rolene Strauss, a medical student, who was among the top five contestants at last year’s Miss South Africa competition.

Le Clos, who became a national hero in July when he won a gold medal in the 200 m butterfly at the Olympic Games by beating American swimming legend Michael Phelps, told new graduates to strive for the impossible. Giving them insight into his remarkable achievement, Le Clos told them nobody had expected him to beat Michael Phelps. “Even I thought it was impossible to achieve. Always have a goal and work towards it,” he told them and said his ambition was to build up swimming in South Africa. Le Clos said he hoped that by 2016 there would be more swimmers making South Africa proud.

Prof. Jonathan Jansen, Vice-Chancellor and Rector of the university, delivered an Olympic-inspired message. Quoting the motto of the modern Olympic Games, ‘faster, higher and stronger’, Prof. Jansen told the new graduates that they had to be better than those who came before them. “I expect my students in a troubled country to learn how to be different, faster, higher and stronger. Faster means efficiency; it means to be responsive to those in need."

Drawing lessons for the country from Le Clos' victory, Dr Khotso Mokhele, Chancellor of the University, told the graduates to choose optimism. Referring to the Marikana mine tragedy, Dr Mokhele said the country was far from taking the last stroke. “Even if it looks as if the curtain is down; remember that final stroke of Chad le Clos and how the great Michael Phelps was defeated.”
