UFS campuses are transforming into research instruments while simultaneously improving campus operations through the Smart Grid initiative.

Imagine living in a smart home. Imagine monitoring your household’s electricity usage via an integrated system that would notify you of your daily electricity use, peak usage times, and tariffs and consumption at the location of the house. As a user, you would be able to take advantage of such information in order to manage your resources in a more efficient manner. This is just one example of what a Smart Grid can do.

The University of the Free State’s (UFS) Faculty of Natural and Agricultural Sciences has teamed up with the Department of University Estates to drive our very own Smart Grid initiative that is transforming the university’s power network into one with full control and monitoring. “A Smart Grid allows for resource optimisation and asset protection, especially in times like these,” said Nicolaas Esterhuysen, Director of Engineering Services. 

Why is it important for our university to have a Smart Grid?
Dr Jacques Maritz, Lecturer of Engineering Sciences at the Faculty, considers a Smart Grid the natural evolution of power grids in the era of Big Data, IoT and Machine Learning. Resources such as electricity, water and steam can now be monitored and controlled to promote savings and the protection of valuable infrastructure. “Aiming towards Smart Grid status, the UFS will improve resource service-delivery to its staff and students, while sculpting a digital twin of its campus’s power grid, consumer network and resource generators,” he added.
  
How will a Smart Grid improve student success?
The integrity, sustainability and continuous supply of energy directly affects the academic project on all three campuses. The implementation of a Smart Grid could allow improved service delivery and reaction time when any utility is interrupted, as well as maintaining the valuable infrastructure that serves the UFS community.

In what way does a Smart Grid improve the lives of staff members?
According to Dr Maritz  and Esterhuysen: “A Smart Grid will support staff to perform their teaching and research duties in a seamless manner, continuously optimising the energy that they consume to enable full comfort and reliability in energy supply, whilst simultaneously generating savings in energy and preventing wastage.”

The UFS already boasts most of the fundamental building blocks associated with the Smart Grid initiative, especially focusing on monitoring, grid protection, centralised and decentralised solar PV generation and software platforms to serve all these domains. However, to integrate all of these domains into one digital real-time paradigm will be a first for the UFS.

Some examples of the UFS smart grid applications currently in practice
Real-time remote monitoring and control that focuses on the following:
- We are able to detect power outages and don’t have to rely on customer complaints. This enables faster response time and fault identification, thus less downtime and an increase in reliability;
- Solar plant generation; 
- Monitoring our standby generation fleet; 
Identifying usage patterns and saving thereof;
Benchmarking buildings in terms of application usage, area or occupancy to determine energy efficiency and identify savings; and condition-based preventive maintenance that will increase reliability while saving costs.

Two lecturers in the Department of Plant Sciences received national recognition for their research at the Women in Science Award 2013 function of the Department of Science and Technology (DST) on Friday 16 August 2013. Dr Marieka Gryzenhout received the award as Young Women Scientist and Prof Maryke Labuschagne was first runner-up in the category Distinguished Women Researcher, both in Life Sciences.

The third award-winner was Rose Lekhooa in the Doctoral Fellowship category. She is studying toward a PhD in Pharmacology and said the fellowship will enable her to attend seminars and workshops internationally.

Friday’s award was the second, in as many months, for Dr Gryzenhout. She received the TW Kambule NRF-NSTF Award as emerging researcher in June 2013. She was the recipient of the International Union of Forestry Research Organizations’ Outstanding Doctoral Research award in 2010.

Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, said, “Dr Gryzenhout represents one of a growing group of very impressive young scientists at the university who are emerging as leading international scholars in their fields.

“Her international leadership in mycology research has already made significant impacts on the African continent and beyond. The university will continue to invest in these young academic stars through its Prestige Scholars Programme where scholars like Dr Gryzenhout are increasingly well-placed to be the next generation of scientific leaders in the world.”

“It as a great privilege to receive the award, especially as second one in this year,” Dr Gryzenhout said. She established a research programme, Mycotoxigenic and Phytopathogenic Fungi, at the UFS. She is president of the African Mycological Association and general secretary of the International Society for Fungal Conservation. She is also a member of the Nomenclature Committee for Fungi – a permanent committee of the International Botanical Congress.

Prof Labuschagne received the African Union Kwame Nkrumah award for life and earth sciences in 2011, and the National Agriculturalist of the Year Award and the National Science and Technology Forum (NSTF) Award for research-capacity development over the last five to ten years, both in 2008.
