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.

Early nutrition impacts on burden of disease

“The first 1 000 days, from conception to two years, is a critical time to ensure that the early environment is optimal to guarantee the best outcomes,” Prof Corinna Walsh, Professor in the Department of Nutrition and Dietetics at the University of Free State (UFS), said. She delivered her inaugural lecture on Nutrition in Transition on 30 October 2017. 

During her lecture, Prof Walsh explained how an unfavourable early environment impacts on the health and well-being of both children and adults. She gave an overview of the prevalence of hunger and food insecurity in the Free State, and described the shift that has occurred from healthier traditional diets to more unhealthy Western diets accompanied by sedentary lifestyles. These patterns are closely linked to the triple burden of malnutrition, including undernutrition, micro-nutrient malnutrition, and obesity. Finally, Prof Walsh highlighted the double burden of disease, focusing on chronic lifestyle diseases on the one hand, and infectious diseases such as HIV/AIDS and TB on the other hand.

“Preparing for this lecture has given me the opportunity to reflect on the almost thirty years of my research journey, a process that I thoroughly enjoyed,” said Prof Walsh.

“It was a privilege to share the work of my research team with fellow colleagues as well as with family and friends,” she said. Prof Walsh is a National Research Foundation C-rated researcher and also served on the Board of the Medical Research Council from 2005 to 2010.

Foundations for health, growth established early
The first 1 000-day window focuses on the time between conception and the second birthday. “This is a critical period for growth and development,” Prof Walsh said. It is a unique period, as the foundations for health, growth, and neuro-development are established. It also focused on the implications of malnutrition, which is the biggest risk factor contributing to the global burden of disease.


Research identifies burden of disease
Her research has made a considerable contribution to identifying the burden of disease in the Free State. “It focuses on both malnutrition and infectious diseases such as HIV and TB on the one hand, and chronic lifestyle diseases such as obesity, diabetes, and hypertension on the other,” she said. The research team have also implemented a number of interventions to address these challenges, including programmes that have assessed the impact of nutrition-education programmes, household food gardens, and nutrition supplementation.
