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.

Dr Oprah Winfrey praises our university

“I came 8 000 miles to say, thank you, Vrystaat!” and “God bless South Africa,” were the words Dr Oprah Winfrey used yesterday to respectively open and close her address to an overflowing Callie Human Centre on our Bloemfontein Campus.

Our university awarded an honorary doctorate in Education to Dr Winfrey during a stately, yet warm and cheerful affair yesterday, which saw the 4 500 seater Callie Human Centre packed to the rafters with adoring fans, staff members and students. 

The honorary doctorate is in recognition of her unparalleled dedication to improving the lives and futures of so many by improving education and ensuring that it is accessible to all. Through her award-winning show, The Oprah Winfrey Show (which concluded this year after 25 years of entertainment and service), and the various charity organisations she has established, Dr Winfrey has harnessed the power of her iconic stature in the struggle to eradicate poverty and make education accessible to all.

The ceremony’s audience was entertained by South African music legend, Ms Sibongile Khumalo, the Bloemfontein Children’s Choir, Bartimea School for the Deaf and Blind’s Sign Language Choir, and several other musical performers as well as dancers.

Dr Winfrey could not hold back her tears when Mr John Samuel, interim Director of our International Institute for Studies in Race, Reconciliation and Social Justice, described her as an “honorary daughter of South Africa”. She proved just how much the country means to her when she joined in the singing of the South African national anthem, Nkosi Sikeleli, despite struggling with the words in some parts.

According to Dr Winfrey, her interest in our university began after she had read an article by Prof. Jonathan Jansen, Vice-Chancellor and Rector, in which he emphasised the need for South Africans to stop accepting mediocrity, if ever the country is to develop to its full potential.

She asked Mr Samuel to convey her message of support to Prof. Jansen and the wheels, which led to today’s great event, were set in motion. 

She also expressed her admiration of the transformation process at our university and our commitment to “reconciliation, peace and harmony”. “What has happened at the University of the Free State is nothing short of a miracle and this is truly what the New South Africa is about,” she said to loud cheers from the audience. 

To emphasise her point, she called the five workers from the Reitz video to the stage and used their forgiveness and acceptance of the students responsible for the video as an example of the healing achieved at the UFS. 

“Having seen this forgiveness has allowed me to expand my vision of what we can be.” She also delivered a message of encouragement and reminded students that anyone, despite their circumstances and background, could become successful and grow to overcome their obstacles, as she had done.

“Anyone can be successful if they put their mind to it, work hard and are diligent,” she said. “We must all strive for more than success, though, and fulfil the highest expression of ourselves as humans by realising who you are and what you are meant to be.”

Following her address, Dr Winfrey answered several questions from our students, giving them advice on, among other things, how to choose a career that is right for them, and good characteristics to look for in leaders and peers.

She also mentioned that several learners from the Oprah Winfrey Leadership Academy, which has its very first group of Grade 12 learners this year, would be visiting our university next month in order to help them select a university to attend next year.
