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.

Highlights of South Campus

We look back on 2016 to pick out the outstanding achievements of our three campuses. Here is a selection of headlines from the South Campus.

Fully online Advanced Certificate in Teaching (ACT)

In July 2016, the South Campus of the University of the Free State (UFS) became the first in South Africa to introduce an online platform for teachers to obtain the Advanced Certificate in Teaching (ACT). This unique platform, entirely online, provides teachers the opportunity to complete these certificates faster than before.

First residence for UFS South Campus
In the second semester of 2016, a new residence, named Legae, was opened on the South Campus, with 146 double rooms and 17 kitchens. The new residence accommodates 250 undergraduate and 20 postgraduate students and has 270 beds, 20 single-bedroom flats, 12 additional single rooms, as well as eight laundry rooms and a drying area. Since the UFS strives to cater for differently-abled people, this residence has two rooms available on the ground floor of Block C for differently-abled students.

The residence is also the first at the university that has a grey-water system installed. This water will then be reused for toilet flushing as well as for irrigation purposes on the campus.

South Campus supplementary schools foster future Kovsies
The Monyetla Bursary Project, in partnership with the UFS and other sponsors, presents an annual Winter School for Grade 12 learners on the South Campus. In addition, a Saturday school for Grade 12s has been in operation since 2007.

“Champion teachers in the district assist learners”

Each Saturday, 650 learners attend the classes. Chris Grobler, a science teacher at Navalsig High School in Bloemfontein, who organises both schools, says: “The 1 200 learners at the Winter School came not only from the Free State but from as far as the North West province, Gauteng, and Eastern Cape. We are very pleased about this, as it means that the image of the UFS is being carried further afield.”

A special feature included in this year’s programme was interpreting services in South African Sign Language (SASL) for deaf students.
