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.

Migration is a developmental issue - experts

“Migration offers more opportunities for economic growth than constraints. It is an integral part of the processes of globalisation and regional integration.”

This was a view shared by one of the speakers, Dr Monica Juma from the Africa Institute of South Africa, during a panel discussion hosted by the Centre for Africa Studies (CAS) at the University of the Free State (UFS) last week as part of the celebrations of Africa Day on 25 May 2010.

The discussion was premised on the theme, Migration and Africa: From Analysis to Action.

Dr Juma said migrants could be assets for host countries or cities because of their resourcefulness. She said they brought along essential skills that could contribute immensely to the economic development of their host countries or cities.

“Governments are beginning to see migration as a tool for development and working together in developing immigration policies,” concurred another speaker, Mr Vincent Williams from the Institute for Democracy in South Africa (IDASA).

He said, if managed properly, migration could yield positive results. He said effective management of migration should start at local and provincial levels.
And for this to happen, he said, the current immigration laws should be amended as he felt they were no longer relevant, because they were based on what countries wanted to achieve in the past.

“Reform national immigration legislation to encourage permanent settlement and improve service delivery mechanisms and bureaucracy to match population movements,” Dr Aurelia Kazadi Wa Kabwe-Segatti, from the Forced Migration Studies Programme at the University of the Witwatersrand recommended.

However, Mr Williams pointed out that policy convergence was a difficult thing to achieve as migration was a politically sensitive issue. He said decisions that countries made on migration could have a negative or a positive bearing on their relations with one another.

Dr Juma also raised the issue of unskilled migrants which, she said, could be a burden to governments. This was reflected in the current South African situation where foreigners offered cheap labour and thus rendered South Africans who demanded higher salaries unemployable. This was a contributory factor to the xenophobic attacks of 2008. What was essentially a labour problem then manifested itself as a migration problem.

Prof. Simon Bekker from the University of Stellenbosch said South Africa was still losing a significant number of skilled professionals to Europe and North America due to an assumption that spatial mobility led to social or economic mobility.

He also suggested that the government should not restrict internal migration but should address the problem of migration across the borders into South Africa.

Senior Professor at the CAS, Prof. Kwandiwe Kondlo, said while the discussion covered a broad scope, there were some gaps that still needed to be filled in order for an all-inclusive view to prevail. One such gap, he said, was to also accord indigenous traditional institutions of governance space in such deliberations and not base discussions on this issue only on the Western way of thinking.

Africa Day is the day on which Africa observes the creation of the Organisation of African Unity (OAU) on 25 May 1963, to promote the unity and solidarity of African states and act as a collective voice for the African continent; to secure Africa’s long-term economic and political future; and to rid the continent of all remaining forms of colonialism. The OAU was formally replaced by the African Union in July 2002.
