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.

“Next time you have three minutes to spare, try to formulate your master’s or doctoral thesis,” says Dr Henriëtte van den Berg, Director of the Postgraduate School at the University of the Free State (UFS).

The much anticipated Three-Minute-Thesis (3MT) Competition took place at the UFS Bloemfontein Campus on Friday 19 August 2016. Diverse and interesting research projects were discussed, giving one a glimpse into months and even years of hard work and dedication.

A learning opportunity for candidates
The 3MT competition is an international event founded at the University of Queensland, Australia. It is divided into master’s and PhD categories.  At the UFS competition, the master’s section was dominated by the Medical and Natural Sciences, in contrast with the PhD section’s focus on Social Sciences. “The competition is a learning opportunity for our UFS candidates,” says Dr Henriëtte van den Berg.

Thought-provoking research presented
Interesting methodologies and research questions sustained the academic excellence the candidates pride themselves in. Saheed Sabiu, PhD candidate and winner, constructed his thesis around, Waste to Health: Corn silk in the Management of Kidney Diseases. “Use corn silk (white fibre around corn) in the same manner as a tea bag, to help manage kidney diseases,” says Sabiu.

Audience members also had the opportunity to ask the candidates questions relating to their thesis topic.

Winners at the event:
•    Master’s winner: Zingisile Mbo
•    PhD winner: Natural/ Health Science: Saheed Sabiu
•    PhD winner: Natural/Social Sciences: Thutukile Jita

The winners of each category received a cash prize and will represent the UFS at the national 3MT competition, hosted by the UFS in November this year.
