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.

Shushing, speaking, politicians, policing

Feminist writer, scholar and previous Kovsie staff member, Prof Pumla Dineo Gqola, recently launched her book at the Bloemfontein Campus. “A Renegade Called Simphiwe” explores the life – and controversy – of singer Simphiwe Dana.

The book tells the story of Dana, a rebellious artist and cultural activist. But it also delves much deeper – into the fabric of our society itself. It questions our expectations and reactions to the things that make us shift in our seats.

The politics of silencing
Artists should not involve themselves in politics. They should stick to what they’re good at. Dana and other artists know this silencing finger being waved at them all too well. It is this mentality that alarms Prof Gqola. “I’m very disturbed by the notion of policing our – especially female – artists.” She pointed out that it is mostly female artists in SA who are put under scrutiny, reigned in and censored. Not only by politicians, though. Our public also quickly steps in when an artist seems to step out of ‘their place’.

The proper place of art
“I’m part of the movement that believes art transforms,” said Prof Gqola. South Africa used to be a fertile ground for protest art. This had an immense impact on political and social transformation. “Then something happened,” Prof Gqola let the words linger. “The arts got divorced from its social transformative power.”

Why has art been publically marginalised?

The question remains.
