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.

Enactus heeds call to be of service to its communities

The future of South Africa is in good hands if Enactus activities are anything to go by. Enactus is an international non-profit organisation bringing together student, academic and business leaders committed to using entrepreneurial action to improve lives. And the Qwaqwa Campus chapter is doing exactly that – changing lives.

Community engagement
This team of enthusiastic and energetic students have touched the Qwaqwa community in more ways than one through their community engagement activities. One such activity was when they adopted the Team Spirit Centre as their partner for development and empowerment.

“Up to now, the chapter has lived up to its purpose of assisting and uplifting the Qwaqwa community. As part of our programme, we identified a problem that we are currently helping to solve,” said Solomuzi Khati, the newly-elected vice president of Enactus University of the Free State.

Skills development
“We have realised that many centres housing orphaned and vulnerable children, like the Team Spirit in Makoane in Qwaqwa, are not sustainable. Our project introduced a business concept to the centre where we helped to plant vegetables so the owner Mrs Manthabeleng could then use and sell at a later stage,” he said. “In the process, students and Mrs Manthabeleng would develop various entrepreneurial, finance and business skills for future use on top of the centre generating income to sustain itself,” he added.

Appointment of Advisory Board
Khati also revealed Enactus was in the process of inviting business and community leaders into their Business Advisory Board. “This is a group of business people who are recruited to serve as mentors for our team. Typically, a Business Advisory Board is composed of 10-50 business leaders in the community. Board members can keep students informed of current business concerns and trends, provide financial or in-kind assistance for projects, critique annual reports and presentations, and provide networking opportunities.”
