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.”

RAG resilience shines despite rain

Winning float for 2017: Armentum, Vergeet-My-Nie,
and Emily

Although the 75th RAG festivities were challenged by ominous weather, in true Kovsie spirit students and organisers still made a gleaming success of the day. 

Students help to create sunny feeling
On 6 February 2017, the annual float-building activities culminated in the handing over of schoolbags to 150 learners from schools in and around Bloemfontein. This took place at the Rag Farm on the Bloemfontein Campus of the University of the Free (UFS), since the morning procession to Twin City Mall in Heidedal had to be cancelled due to bad weather.

“It is of course a huge disappointment to all of us that the events had to be cancelled, but we are grateful for the rain,” said Karen Scheepers, Head of Kovsie Rag Community Service and Assistant Director: Student Affairs.

The evening KFC Rag procession took place as planned, with students having the option of taking part despite the weather. Unfortunately, the Chevrolet Music Festival had to be cancelled.

“The very important actors of today are our students who have worked long hours to build the floats and who have worked together to make this rainy day on the outside feel sunny inside,” said Prof Francis Petersen, incoming UFS Vice-Chancellor and Rector, when he addressed the crowd at the Rag Farm. Prof Petersen will take up office on 1 April 2017.

Armentum, Vergeet-My-Nie, and Emily take honours
Armentum, Vergeet-My-Nie, and Emily Hobhouse were the overall winners of the 2017 Rag float-building. “It was worth the hard work. Always remember to ask for advice during float-building,” said Pieter Kotze, RC Rag of Armentum residence on the Bloemfontein Campus. “I also want to thank both the RC Rag from Vergeet-My-Nie and Emily Hobhouse.”

The float theme was Proudly South African, and the winning float encapsulated it with local flavours such as Chappies, a Rooibos tea box and a Lion matchsticks box. They also went the extra mile by incorporating each hostel’s logo within a Chappie design.

The Central Rag Committee would like to thank all their sponsors who made the events possible. The Rag Coronation Ball will take place on 17 February 2017, where the new Rag Queen and Mr Rag will be crowned.
