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.

UFS unveils Women’s Memorial Garden

Our university rewarded the hard work of women at the university by unveiling a Women’s Memorial Garden at our Bloemfontein Campus on National Women’s Day, 9 August 2011. University Staff, students, some members of our Council and other guests gathered at the university for the unveiling of the new memorial garden.

Prof. Driekie Hay, Vice-Rector: Academic, told the somewhat 50 people at the unveiling that it was a historic day for the UFS, as this was a sign of how far the university have come. Prof. Hay told the women at the function to be proud of their achievements. She said the purpose of Women’s Day was to celebrate the historic struggle and sacrifices of all South African women, especially those who fought against racism and sexism.

The Women’s Memorial Garden consists of a botanical garden with more than 80 plant species. In the middle of the garden is a stone statue with a wild fig tree planted within. Prof. Hay told the guests that the tree’s numerous seeds represent unity and is an indication of real understanding, knowledge and faith, characteristics women at our university should pursue to ensure a sustainable and prosperous future for the UFS. The University leadership will now embark on a process to identify and recognise women from the university community who have made significant contributions during its 107 years of existence.

The memorial garden was designed by Habitat Landscape Architects. Mr Siegwalt Küsel, an architect at the firm, said the garden was developed to be a living monument to women. He said they hope that the garden will become an active learning space for visitors.
