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.

Afrikaans speakers should think differently, says Coenie de Villiers

Do not ask what can be done for your language, but what your language can do for others. With this adaptation of the late John F. Kennedy’s famous words, Coenie de Villiers stressed that the onus for the survival of their language rests with Afrikaans speakers.

According to the television presenter and singer, the real empowerment of Afrikaans does not necessarily take place in parliament. He was the speaker at the DF Malherbe Memorial Lecture, presented in the Equitas Building on the University of the Free State Bloemfontein Campus on 24 May 2016. The lecture by De Villiers, a UFS alumnus, was titled Is Afrikaans plesierig? ’n Aweregse blik.

Government not the only scapegoat
He used Kennedy’s famous phrase, Ask not what your country can do for you, but what you can do for your country, as framework. “I believe that, if we reverse our sights and do not ask what the world can do for Afrikaans, but ask for a change what Afrikaans – and in particular each and every user thereof – can do for others, then we have, in good English terms, ‘a fighting chance’ that Afrikaans will not only survive, but that it will thrive.” He said it would be too easy to just blame the government’s language policy and/or its lack of application for the language’s uncertainties.

Speakers should act correctly
He said the actions of speakers, sometimes motivated by a love for the language, often causes more damage. “It is not the language that should squirm under the microscope. It isn’t Afrikaans that is being tested: it is us, the speakers, writers, thinkers, doers, and tweeters of the language that are being measured.”
De Villiers believes one should stand up for your language without hesitation or fear, but not necessarily in the middle of the road, and never in such a way that you abandon the moral compass of humanity.

Language will live on

He told the audience that Afrikaans speakers should maintain their language every day with the merit, humanity, and respect that they believe the language – and they themselves – deserve. The language will “live on as long as we use it to laugh, and talk, and sing, and do not kill it off with rules and directives.”
