Smart Grid to change the way UFS uses energy resources

SmartGrid_read more — 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.

Rag teamwork leads to Armentum, Emily's float

2016-02-04

Perhaps the residences Armentum and Emily Hobhouse were thrown into the deep end, but they still wanted to prove a point.

This is according to Hanko Minnaar, Residence Committee member for Rag at Armentum, shortly after the residences were announced as overall float winners of the University of the Free State (UFS).

According to Minnaar, Emily Hobhouse and Armentum overcame the challenge of building a float as a two-residence team, while most of the other hostels were in teams of three.

On 30 January 2016, after about two weeks of hard work and sweat, the residence twosome was named the winner at the Bloemfontein Campus.

“I am very proud. We couldn't have asked for more,” Minnaar said, after the residences Armentum and Emily Hobhouse celebrated their victory with house songs. “Anything is possible through teamwork.”

Tom and Jerry, Olaf and a Steri Stumpie

The theme for this year was “Cartoons, Animation, and Children's Snacks”. Among other items, Armentum and Emily Hobhouse had Tom and Jerry, Olaf from Frozen, a Steri Stumpie, and a box of Astros on their float.

“We thought hard about what we wanted,” Minnaar said.

“We also asked some children, and they said that Tom and Jerry is a favourite, and Olaf has always been a winner as well. And Steri Stumpies, of course. Who doesn't like Steri Stumpies?” The residences Marjolein, Veritas, and Akasia were second overall, with Karee, Vergeet-My-Nie, and Sonnedou third.

Colourful processions

The events of the day started off with a morning procession from the Pelonomi Hospital to the Twin City Mall in Heidedal, where students and the community celebrated together, and meals were distributed.

The evening procession, from the Tempe robot in Nelson Mandela Drive to the Old Grey Sports Grounds, was greeted by hordes of spectators along the way.

Artists and Co captivate audience

In the evening, music lovers were entertained at Old Grey Sports Grounds by the legendary artists Vusi Mahlasela, the talented Karen Zoid, and an energetic Francois van Coke.

Local bands, Rise in Red and Simple Stories, added to the excitement. To top it all off, a special laser show made for a colourful visual bonus, coupled with great sound.
