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.

Kovsie Biggest Braai a huge success

Even though Braai Day is celebrated nationally in September, students at the University of the Free State (UFS) had their own braai day. The Kovsie Biggest Braai was the biggest student community event of the year.

Takudzwa Nyamunda of the International Student Council said the idea for the braai came from the International Student Association as a social cohesion event for international students. “When the idea was presented to my office we realised the potential for such an initiative to be not just for students but for the whole Kovsie community.”  

They realised there were not a lot of social cohesion events on campus where students and staff could just take a day to relax and embrace the feeling of being a Kovsie. He said he believed the braai could provide the right platform. The main objective of this project was to make it an institutional event with aspects of fundraising for the future. 

Colleges made KBB a success 
An estimated 3500 people attended the festivities on Red Square on 12 August. “We used the college format for the braai and it was set in the form of a challenge between the five colleges, but one of the colleges pulled out,” Takudzwa said. The colleges that did participate made a big contribution towards the success of the event and did all the braaing and selling. 

Creating new Kovsie traditions 
The idea behind the pilot project is that it becomes an annual event which in turn will form part of a new Kovsies tradition. “It received endorsement from top management therefore I believe it will form part of the Kovsie calendar for years to come,” Takudzwa said.
