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.

Neonatal Care Unit receives donation to expand capacity
2015-10-28

  

With the best care and technology available,
the survival rate of premature
babies is about 85%. The neonatal intensive
care unit at the Universitas hospital can now
expand its capacity thanks to a donation of
R1 million by the Discovery fund.

The smallest people need the greatest care. This care is being provided by the neonatal unit in the Children’s Wing of the Universitas Hospital. This project of the University of the Free State (UFS), under the leadership of Prof Andre Venter, has led to several miracles regarding child health since its inception.

Now, thanks to a donation of R1 million rand from the Discovery fund, this unit can expand its capacity and treat more premature babies.

About 14% of babies in South Africa are born before the 37th week of pregnancy. These babies are born with a very low birth weight, and are in need of critical care. The neonatal intensive-care unit at Universitas Hospital is currently equipped to take care of about 14 premature babies at a time, from birth to discharge. However, because of the high incidence of premature births in the hospital’s service area, the unit needs about 45 beds.

The aim of the Children’s Wing Project is to expand the neonatal intensive-care unit in order to meet the demands of the hospital’s service area, which reaches as far as the Southern Cape. The Discovery Fund recently donated R1 million to the project, which will be used to expand the capacity of the neonatal intensive-care unit.

“With the best care and technology available, the survival rate of premature babies is about 85%. Without this, half of all premature babies would die,” says Prof Venter, Head: Department of Paediatrics and Child Health at the UFS.

“This is the reason why private and public partnerships, such as the one with Discovery, are essential to make specialised services available to the most vulnerable people. Discovery has made a significant contribution to the project without which we would not have been able to expand the capacity of the unit
