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.

Cedric Nunn’s latest photographic exhibition, Unsettled: One Hundred Years War of Resistance by Xhosa Against Boer and British, opened on 25 May 2016 at the Johannes Stegmann Art Gallery of University of the Free State, and will run until 17 June 2016. Since 2014, the exhibition has travelled through South Africa and the USA as well as Germany.

The photographer, documentary film-maker, and artist’s photographic journey was launched in the early 1980s in Durban. In 2011, he won the first FNB Joburg Art Fair Award.

Narratives of the victors and the vanquished

Unsettled deals with the nine wars that Xhosa people were subjected to between 1779 and 1879 in their fight against Afrikaner and British colonial settler forces. Nunn’s art seeks to instigate social change, and highlight lesser-seen aspects of society.

The work emanated from his awareness of a notable gap in the telling of this piece of South African history, as well as the fact that, to date, little has been done to memorialise these acts of colonial aggression and Xhosa resistance. He decided to document the land where these struggles took place.

“Through revisiting this painful past in the contemporary scenes of today, this work attempts to place the present in its factual context of dispossession and conquest,” said Nunn.

Unsettled
forms the first component of what will be a trilogy. The next component will address the legacy of colonial dispossession through “bringing ‘the first inhabitants’ back into the picture by giving a select number of self-describing Khoi, Griqua, and San or Bushmen a contemporary face and presence”. The final component will look at slavery.
