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.”

Shimlas shock Tuks by staying calm

He has never been involved in a match like this in his rugby career.
This is what Neil Claassen had to say about his team’s performance on 15 February 2016, when the Shimlas came up with one of the biggest fight-backs in the history of the Varsity Cup in Pretoria. According to the Shimlas Captain, his bench had a great impact, and this helped in shocking Tuks with 47-46 towards the end. This came after Tuks had been leading 43-15 in the 44th minute.

Great fighting spirit
The Shimlas' fighting spirit, and a new Varsity Cup points system in which converted tries may count up to 11 points, enabled them to wipe out this deficit.
“It was a tough match, especially after being so far behind,” Neil said.
“Coach (Hendro Scholtz) told us during half-time (when we were 15-36 behind) that we should stay calm."
“We weren't completely out of the game. We knew that if we eliminated unnecessary mistakes, we could make it.”

Impact from bench
This is the second consecutive match - the other was against Ikeys in Cape Town - where the Shimlas’ substitutes swayed the match. “The bench made a big difference,” Neil said. “We also scored an 11-point try, which helped a lot.”
The Shimlas’ fullback, Marco Mason, was named Player of the Match. He succeeded with a tricky conversion to gain victory for his team.

Injuries
The eighth man, Nardus Erasmus (knee) and flanker, Fiffy Rampeta (eye socket), sustained injuries, but should be able to play in the first home game against the Madibaz on 22 February 2016. The injured scrumhalf, Zee Mkhabela (concussion), could return for this match.
Shimlas are second on the log, with nine league points after two away matches. Maties has ten league points.

Young Guns get stuck
The University of the Free State (UFS') Young Guns got stuck 8-14 against Tuks in Pretoria on 15 February 2016.
Vishuis, the UFS's residence team, will start their onslaught in the residence league against Dagbreek in Stellenbosch on 22 February 2016.
