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.

Freedom of religion, a constitutional right and area of global concern

Freedom of religion is enshrined in the South African Constitution, states that everyone has the right to freedom of religion, which more specifically entails the freedom of conscience, religion, thought, belief and opinion. It makes provision for the protection of religious communities in South Africa. Consequently, the maintenance and protection of such a right is of fundamental importance.

Prof Shaun de Freitas, Associate Professor of Law at the University of the Free State (UFS) specialises in constitutional law, with a specific focus on the right to freedom of religion, and has produced several publications in the field. The latest is titled “Transcending the Private-Public School Divide in the Context of the Right to Freedom of Religion in South Africa”, Chapter 19, in Religious Freedom and Religious Pluralism in Africa – Prospects and Limitations published by Stellenbosch University in 2016.

Prejudice a challenge in all societies
There are numerous challenges faced by religious groups around the world concerning prejudice, association with terrorism and political power and influence. Therefore, research in this field becomes important in helping to uphold the rights and freedoms of religious minority groups, to be able to foster understanding between communities.

Balancing responsibility and religious rights
His current focus is on challenges that have arisen in South Africa, more specifically pertaining to the right of medical practitioners to object conscientiously towards participating in certain medical procedures, the parameters of freedom related to religious associations and the inclusion of religious expression in public schools. These matters are also relevant to many other parts of the world (including, ironically enough, those democratic societies that endeavour to make diversity flourish).
