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.

State of our campuses: UFS Qwaqwa Campus temporarily closed until 18 April 2017
2017-04-03

The senior leadership of the University of the Free State (UFS) has decided to close the Qwaqwa Campus on Tuesday 28 March 2017 due to student protests regarding provisional registrations. Academic activities will resume on 18 April 2017. 
 
The protests were preceded by a meeting of the campus management with the Student Representative Council (SRC) on 22 March 2017 to discuss issues pertaining to students who are provisionally registered – especially those students who are provisionally registered and awaiting the outcome of their appeals to the National Student Financial Aid Scheme (NSFAS).
 
On 27 March 2017, the SRC handed a memorandum to the campus management, requesting assistance in cases that are on appeal with NSFAS. The students also demanded extension of the provisional registration deadline of 31 March 2017, and that a fundraising plan should be implemented for financially needy students. The campus management made a commitment to respond within the deadline stipulated in the memorandum.
 
After the meeting, violence erupted when a group of students started intimidating students, barricading the entrance to the campus, and damaging university property. An interdict was served by the Sheriff later the same afternoon and additional security was deployed. On 28 March 2017, the violent protests and barricades spilled onto the provincial road to Phuthaditjhaba and several cars were damaged. This led to the arrest of a number of students by members of the South African Police Service for the contravention of the High Court order and for public violence. The students have since been released.
 
Due to the imminent threat to the safety of staff and students on the campus, the senior leadership decided on 28 March 2017 to evacuate the residences and to close the campus temporarily until 18 April 2017.
             
“It is unfortunate that the students resorted to violence without waiting for the campus management’s response to the memorandum of 27 March 2017. What makes the situation difficult is the fact that students on provisional registration who are waiting for the outcome of their NSFAS appeals, are dealing directly with NSFAS. This makes it difficult for the university to intervene,” says Mr Teboho Manchu, acting Principal of the Qwaqwa Campus.
 
The senior leadership of the UFS is aware of the video clip on social media this week, where a student is allegedly beaten by security guards on the Qwaqwa Campus. The senior leadership condemns this deplorable incident. An investigation is underway to determine the nature and cause of the incident. Appropriate steps will be taken once the outcome of the investigation is available.
