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.”

Prestigious Helgaard Steyn Prize to be awarded to UFS composer
2010-11-08

 Hans Huyssen.

The composer Hans Huyssen, affiliated with the Department of Music at the University of the Free State (UFS), is to be the current recipient of the prestigious 2010 Helgaard Steyn Prize, the prize-winning work being Huyssen’s Proteus Variations (2006).Annually this award is administered and presented to a selected composer, painter, author, or sculptor by the Universities of the Free State and the North-West on a rotating basis. The judges for this year’s prize were Prof. Bertha Spies, Research Fellow, North-West University, and Professor Extraordinary, University of Pretoria, and Mr Noel Stockton, Senior Lecturer at the University of the Free State.

Hans Huyssen’s musical activities encompass the diverse poles of early and contemporary Western and African music, often in an attempt to assimilate the essential qualities from all these fields. His intense focus on contextuality suggests that he approaches music as a profoundly social force which has a particular role to play in our ‘new’ diversified South African society.

The Proteus Variations were commissioned by the Deutsche Welle Radio for the South African National Youth Orchestra 2006, and were premiered at the Beethoven Bonn Festival during 2006. These variations are described by the composer as “a musical representation of South Africa’s manifold Proteaceae”, named for the Greek god Proteus who, at will, was capable of assuming a spectrum of shapes and appearances. As the composer states: “It is worth noticing that a Protea is South Africa’s national flower. What could be more appropriate in providing a key to an opposite perception and understanding of the country’s diverse cultural expressions? In this regard it is my hope that the Proteus Variations may contribute a little to the wide scope of cultural responses necessary to begin to do justice to the extremely rich tapestry of our immediate cultural and natural surroundings”.

The prize of R170 000 will be awarded to Hans Huyssen by a representative of ABSA Trust, who is one of the trustees of the Helgaard Steyn Trust, in Bloemfontein on 8 November 2010.
