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.

Springbok call-up tops Rhule’s dream season

We can add yet another name to our already impressive list of Springbok rugby players. Raymond Rhule has been included by Heyneke Meyer as one of five uncapped players for the Springboks’ upcoming European tour.

The nod from the selectors caps a tremendous year for the Ghanaian-born star. The former Technical High School Louis Botha pupil and current UFS student rose through the South African rugby ranks at a rate which can only be described as spectacular.

He was part of the Shimla team which competed in this year’s under-20 and senior Varsity Cups that culminated in inclusion in the victorious South African team at the under-20 World Cup.

Since then, he has been a fixture in the Free State Cheetah team in both the Vodacom Cup and the premier local rugby competition, the ABSA Currie Cup, gaining praise for his performance from the public and rugby experts along the way.

The 19-year-old wing has been the stand-out performer for a troubled Free State Cheetahs outfit, who had to see off the Eastern Province Kings in relegation playoffs to stay in the top division of the ABSA Currie Cup.

In an impressive season, Rhule scored eight tries, earning him the spot as the competition’s top try scorer.

Among a raft of awards, Rhule was announced as the UFS Junior Sportsman of the year for 2012 in October and has been nominated as the South African Rugby Union’s (Saru) Young Player of the Year.
