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.

UFS enhances Geography in schools
2015-05-11

The Green Box

The Department of Geography at the University of the Free State (UFS), in association with the Society of South African Geographers (SSAG), is doing their part in providing curriculum support to schools. Dr Ruth Massey and Anneri Pretorius are the project managers of Green Box, an initiative to advance Geography in schools.

The Green Box supports the intermediate phase of schooling (Grades 4, 5, 6). According to Dr Massey, the worksheets and activities provided in the Green Box are aligned with the Curriculum and Assessment Policy Statements (CAPS) and the new curriculum. “These worksheets are divided into three themes: map work, physical Geography, and human Geography.

“Map work includes symbols and keys, grid references, and compass work whilst physical Geography focuses on water and waste, biodiversity and conservation, and weather and climate issues. The human Geography theme has a focus on population, rural and urban development, migration, food and farming, and transport and trade,” she said.

Each worksheet has a fact sheet section which teaches theory on the specific topic (linked to the curriculum), an activity section (all resources needed for these activities are provided in the box), and a ‘take it home’ section for further learning and practice at home.

The Green Box is a recycled plastic crate that comprises worksheets, training materials, visual aids, and resources for teaching, learning, and active engagement in Geography classes.

Also included in the box are a felt story board and characters (that link with the worksheet activities), the ‘Climate Change memory game’ (which enhances learner’s memory capabilities and teaches various climate change facts) and the ‘Sustainable Development puzzle game’ (which teaches about the social, biophysical, economic, and political elements of Sustainable Development, and how they overlap).

“All items in the box are locally sourced, robust, and without copyright,” said Dr Massey.

The project is focusing on 10 under-resourced schools in the Bloemfontein area. Each school has received three boxes (one for each grade of the Intermediate Phase).

Dr Massey said: “This box is to be shared among the teachers. The Green Boxes were distributed at a training and information workshop held at three central schools in the various districts. These workshops introduced the teachers to the contents of their box, and provided basic training on the worksheets and the activities provided.”

“The schools will be joined up with ‘Box Buddies’ at more resourced schools in Bloemfontein. These buddy schools will assist in support and in replenishing the box’s stationery, etc. when needed.”

“Monitoring and evaluation will take place for six months after the boxes have been distributed. This will ensure support to, and the sustainability of, the project.” The Green Box project was made possible through a grant from the Society of South African Geographers (SSAG).
