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.”

Housing strategy must accommodate special needs
2005-10-17

Dr Mark Napier of the Council for Scientific and Industrial Research (CSIR) 

South Africa’s housing strategy must give attention to people with special needs, including people with disabilities as well as people living with HIV / AIDS and those in poverty.

This was the view expressed by Dr Mark Napier of the Council for Scientific and Industrial Research (CSIR) during his recent presentation to the Housing Research Day organised by the Centre for Development Support (CDS) at the University of the Free State (UFS).

Dr Napier previously worked in the national Department of Housing and was involved in shaping the recently launched “Breaking New Ground” housing strategy of Minister Lindiwe Sisulu. 

He said the changing social and demographic trends in South African society, especially after 11 years of democracy, required more flexibility in housing delivery to address the housing needs of different groups of people.  “For example, there are people who wish to or may be required to be spatially mobile because of their work or other reasons. There are also those communities who are vulnerable to disasters,” he said.

According to Dr Napier, housing delivery faced a number of challenges which needed to be addressed, including:

  • the withdrawal of larger construction firms
  • perceptions of low profit margins in the private sector
  • the slow process of developing an emerging contractor sector
  • access to bridging and other finance
  • the ability to retain capacity and expertise mainly at municipal level
  • the acquisition of well located (especially inner city) land

Dr Napier said the new housing strategy – which is called “Breaking New Ground” – tries to go beyond the provision of basic shelter to the establishment of sustainable settlements. It is also tries to be more responsive to housing demand rather than being supply led.

 The new strategy also allows for greater devolution of power to municipalities in the provision of housing, through accreditation to manage subsidies, Dr Napier said. 

He said a survey of people who had benefited from government’s housing programme had shown mixed results, with beneficiaries reporting a sense of security, independence and pride.  Although the location of the houses was poor and there were increased costs, most beneficiaries said they were better off than before, according to the survey.  Beneficiaries also highlighted the problem that they had very little personal choice between houses, sites or settlements.

There was also the perceived failure of developers and municipalities to repair defective houses or adequately maintain settlements, the survey found.
Many beneficiaries also reported that they felt unsafe in their settlements as well as in their own houses.

Prof Lucius Botes, the director of the Centre for Development Support, said the research day highlighted the Centre’s ability to interact with real problems faced by communities, by government, the private sector and civil society.  “This is how we can ensure that the UFS is engaged through our research with our people’s problems and challenges and enables the UFS as a place of scholarship to assist in finding solutions,” Prof Botes said.
