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.

Justin J. Kennedy has been appointed as the Manager of the new Programme in Personal Excellence. The programme is hosted in the Centre for Business Dynamics, the commercial unit of the Business School.

He studied at Rhodes University and the University of the Western Cape (UWC) and his research has been published in various health-related publications. His D.Psych. at the University of California migrated into a Ph.D. with research partner DiscoveryHealth.

While in New York, he was part of the research laboratory Helicor that developed the world’s first hand-held medical device for measuring heart-rate variability of the peripheral nervous system.  This device forms part of the programmes offered to control stress and improve cognitive performance as per clinical trials at the UCT Department of Human Biology. This programme evolved into developing the M.Sc. course work on occupational stress and Ph.D. student supervision.

The programme will launch during the university's Beneficiary Programme for Academic Heads of Department, and will focus on the neuro-economics of stress resilience.

Justin’s most recent research is peer review for an international leadership journal where he has presented evidence on how people can improve their cognitive performance and working memory by building functional stress resilience. The overall aim of the programme is to not only reduce stress, but to improve ability to be excellent at work.  Clinical results have shown it is beneficial for performance anxiety, insomnia, migraine, hypertension control and improved ability at cognitive tasks.  The aim of his work is to ensure that simple and practical skills provide academics, students and corporate participants with enduring, functional techniques that are easily applied in their working lives.

The programme has three roles: to offer services that equip students and academics; consulting services to corporate clients, financial groups and private hospitals; and publication of results in peer-reviewed journals. 

This initiative also envisages offering a postgraduate qualification and selected coaching qualifications.  For more info about corporate interventions and programmes open to students and academics, please contact Ansie Barnard at barnardam@ufs.ac.za.
