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.

Doll parent project exposes learners to real-life issues of responsible reproductive health

With the alarming rate of teenage pregnancies in secondary schools, a concerned teacher approached University of the Free State (UFS) School of Nursing in 2013, and in 2015, the Reproductive Health Education Project (RRHEP) was established in collaboration with fourth-year Midwifery students, the Princess Gabo Foundation and the UFS Community Engagement Directorate.

Empowering learners to make responsible reproductive health choices was the primary objective, which got final-year nursing students involved in the Doll-Parenting Project as part of their Service Learning Module. To simulate parenting, boys and girls in Grade Eight were given dolls to take care of as their “baby” for a given period of time. After an information session with parents and guardians, the project took off at Moroka High School in Thaba Nchu and Lekhulong High School in Mangaung. The Princess Gabo Foundation, an NGO operating in the Thaba Nchu community, which supports maternal health programmes, provided the dolls, kangaroo wraps, and diaries in which learners recorded their daily experiences of caring for a baby.

Teen parenting – a challenging experience

Learners were required to calculate how much it would cost to care for a baby, the cost of buying nappies, formula milk (if not breast feeding), doctor’s visits, and medicine. The project was supported by teachers in various subject classes, and learners were encouraged to express themselves through writing of poems or essays about how it feels to be a teen parent.

Dr Delene Botha, lecturer at the School of Nursing, said there was a need to establish a sustainable research project that would attract funding. By adding some of the missing components and drawing on other disciplines such as Sociology and Psychiatry, the project was expected to be extended to meet the needs of other stakeholders including teachers, parents and the community at large.

With cellphones and data provided by the Community Engagement office, the “parenting practice” involved receiving SMS messages from nursing students during odd times of the day to remind them about the needs of the baby; such as wet nappies, the “baby” not feeling well and to be soothed.

Sensitising learners yields success

In evaluating their performance, appointed “police learners” became the eyes and ears of the community to observe and report on how “parents” treated their “babies”. Statements from participants and feedback showed Incidences of negligence and the feeling of embarrassment from being a teen parent. The report indicated that learners felt that having a baby while still at school was not a good idea. The project concluded with a debate on the subject.

As part of the programme, a group of postgraduate Education students from Rutgers University in the US, visited Chief Moroka High School and received first-hand information from their interaction with the learners from which they created digital stories of their Community Engagement experience and took these back with them.
