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.

“Africa Month provides an opportunity
to every student and staff member to
commemorate African unity and celebrate
our rich cultural heritage, diversity,
energy and social dynamism.”

The University of the Free State (UFS) celebrates Africa Month to commemorate African unity and praise cultural heritage, as well as to take ownership of the future of the continent. According to Prof Heidi Hudson, Director of the Centre for Africa Studies, these are reasons to take part in the festivities.

Formation of Organisation of African Unity

Africa Day is the day on which Africa observes the creation of the Organisation of African Unity (OAU) on 25 May 1963. A total of 32 independent African states attended the formation.

The OAU’s aims were to promote unity and solidarity of the African states and act as a collective voice for the continent, in order to secure Africa’s long-term economic and political future and to rid it of remaining forms of colonialism. The OAU later gave birth to the African Union, which formally replaced the OAU in July 2002.

Prof Hudson says celebrating Africa Month forms part of her centre’s institutional mandate to promote an African focus in research, teaching, as well as public debate.

“Africa Month provides an opportunity to every student and staff member to commemorate African unity and celebrate our rich cultural heritage, diversity, energy and social dynamism. Secondly, by participating we all begin to take ownership of our future on this continent.”

She adds that Africa month provides a platform for reflecting on past experiences and achievements, as well as to critically assess the failures, challenges and the lessons learnt for the sake of a better future for the continent’s people.

Working relations across the continent

The UFS has working relations with universities, embassies and consulates in African countries such as Zimbabwe, Mozambique, Botswana, Zambia, Kenya, Namibia, Nigeria, Ghana, Uganda, and Tunisia.

Five cooperation agreements exist – they are with the Botho University (Botswana), Greater Zimbabwe University, Universidad Eduardo Mondlane (Mozambique), Trinity Theological Seminary Ghana, and Namibia Evangelical Theological Seminary.

According to Kanego Mokgosi, Senior Officer at Internationalisation, there are also working relations between the university and The Council for the Development of Social Science Research in Africa, Swedish International Development Agency and The United Nations Educational, Scientific and Cultural Organization. All of these focus on research development in Africa.

Most of the international students at the UFS come from the Southern African Development Community (SADC) and the continent. It hosts 1393 students from SADC countries.

“The UFS employs SADC protocol guidelines which, among others, enjoin SADC universities to admit at least 5% of their student population from the SADC region,” says Mokgosi.

Memorial Lecture by Dr Zeleza

On 24 May 2017 the Centre for Africa Studies hosted an Africa Day Memorial Lecture by Dr Paul Tiyambe Zeleza, the Vice Chancellor (President) of the United States International University Africa, Nairobi, Kenya.

The UFS library, in collaboration with the Department of English and the Office of International Affairs, also celebrated Africa Day on 25 May 2017. They hosted a conversation on the Land Debate in South Africa, together with the launch of a book titled White Narratives: The depiction of Post-2000 Land Invasions in Zimbabwe by Prof Irikidzayi Manase. He is an Associate Professor in the Department of English.
