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.

Kovsie-Alumni Trust provides financial support to gifted young persons
2009-07-08

 
Kovsie-Alumni Trust of the University of the Free State (UFS) provides financial support to gifted young persons. This year, the Trust has already granted R24 000 to students with disabilities and R28 500 to ad hoc applications for financial support. Amongst others, financial support of R224 888 was given to students from the Alumni Donation Funds. The contributions of generous donators to the Trust Fund are used to award academic, cultural and sport bursaries to deserving prospective as well as current Kovsie students. Here are, from the left: PK Nkate, a blind honours student in Business Management, who received R6 000 from the Trust, Ralph de Kramer, who received R3 500 for his ad hoc application; back: Adv Seef Hefer, Chairperson of the Trust, Ms Francis Hoexter, member of the Trust, Leendert Kramer, who received R60000 for his ad hoc application and Mr Ryno Opperman, member of the Trust. Other bursaries were awarded to Eleanor Bernard and Nandi Venter, Master’s students from the Department of Afrikaans and Dutch, French and German, who each received half of the NNP bursaries with the total value of R20 000 and Magteld Smith, a blind Ph.D. student in BA to whom the Sapcor Bursary was awarded. Carien Gordon, Geoff Bezuidenhout and Ilana van der Merwe received R6 000, R3 500 and R3 500 respectively, according to their ad hoc applications.
