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.

Ex-Kovsie swimming legend passes away
2013-04-03

03 April 2013

The University of the Free State (UFS) expresses its condolences to the friends and family of former Kovsie and swimming legend, Dr Karen Muir. Dr Muir passed away on 2 April 2013 in Mossel Bay, after battling cancer for a number of years.

Dr Muir enrolled at the UFS in 1971 and completed her MB ChB in 1977. Despite her academic prowess, it was in the swimming pool that Dr Muir achieved even greater acclaim.

Dr Muir was the youngest person ever to hold a world record in swimming or any other international sporting discipline. As a twelve-year old in 1965, she beat the then record time in the 110-m backstroke. After her initial success, she went on to set fifteen more world records in a variety of swim strokes.

During her career she won 22 South African Championships, three United States National Championships and was inducted into the International Swimming Hall of Fame in 1980.

After matriculating in 1970 from Diamantveld High in Kimberley, she retired from swimming to focus full-time on her medical studies. Since then she practised as a physician in Africa and from 2000 onward, in Canada, after relocating.

“We as a faculty mourn her passing and extend our deepest sympathy to her loved ones, family and friends,” said Prof Gert van Zyl, Dean of the Faculty of Health Sciences.
