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.”

Physical Planning lives in recaptured space
2014-06-18

When the Department of Physical Planning decided on a new office premises, the team decided to tackle the project with an overarching theme – recycling.

It is important for Physical Planning to not only dictate to other departments on campus, but to set the example themselves,” says Nico Janse van Rensburg, Director: Physical Planning at the UFS. 

Recaptured space

New office space on campus is simply not available. It was therefore decided to recover space and a store room was identified. “Fortunately, the storage area had ceilings. However, it was dilapidated and was sagging all over. To divert attention from the ceiling, we painted it in a dark colour and the walls white.

“All wiring was also done superficially. It draws the attention away from the uneven surfaces and simplifies work on the wiring. Instead of trying to hide it, we made a focal point of it,” says Janse van Rensburg.

Recycled building materials

Lots of the building material that was used to convert the storage space into offices, was recovered from other building projects on campus. Material that would normally be discarded was utilised creatively to not only serve a practical purpose, but also an aesthetic one.

A laboratory basin was used as wash basin. Remaining parts of granite slabs from other sites were utilised as top for the basin. Existing toilets were also reused. To enhance the atmosphere, new taps in an affordable, but durable range were installed.

Recycled furniture

We rambled through every possible store room to find furniture. Tables were simply sanded and varnished and look better than new. Even the cabinet at the entrance was saved from wind and weather and reused.

Hot and smart

Only one screen wall was built. It was left in raw brick, unplastered and unpainted to contribute to contrasting textures. Existing walls were left painted or unpainted as it was before.

“The environment that was created breaks down several existing perceptions. Such as the perception that everything has to match; everything has to be plastered and painted and many others. This is an example of how different materials can be combined to create a lively environment.

“Staff members have already moved into their new offices and are very satisfied,” says Janse van Rensburg.
