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.

South Campus supplementary schools foster future Kovsies
2016-07-13

The Monyetla Bursary Project, in partnership with the University of the Free State (UFS) and other sponsors, presents an annual Winter School for Grade 12s 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”

Chris Grobler, a science teacher at Navalsig High School in Bloemfontein, is the organiser of both schools. He says, “I saw it as a tragic state of affairs that those offering bursaries and the bright learners from our formerly disadvantaged schools were not meeting up with each other.”

The first year saw 300 learners attending, with five subjects being presented. This tally has since grown to 650 learners each Saturday, with 11 subjects being presented, including Business Studies, Computer Applications Technology (CAT), Geography, Maths, and English.

“Our vision was to get champion teachers in the district to assist learners to qualify for university bursaries,” says Grobler. The project has succeeded in attracting educators with extensive experience as chief markers or even subject advisors in the Department of Education.

Wider reach

“This year, the 1 200 learners at the Winter School hail not only from the Free State but also from as far as North-West, Gauteng, and the Eastern Cape.” Grobler says, “We are very pleased about this, as it means that the image of the UFS is being carried further afield.”

Lesego Modisele, one of the visiting learners from Parys, says, “I like how they brought in teachers that are heads of their subjects, who are very experienced and help us a lot. They explain how exam papers are set and which important things to focus on.”

By means of the Schools Partnership Programme (SPP), 250 learners from Thaba Nchu and Botshabelo have also been assisted. Katleho Setloho, who was one of these students, is currently a medical student at the UFS.

A special feature included in this year’s programme is interpreting services in South African Sign Language (SASL) for Deaf students. As an added bonus, a disc of the sessions in SASL is being compiled for English, Mathematics, and CAT, with plans for it to be distributed to the deaf community in the rest of South Africa via the UFS.
