Best Presentation win for Honours student Rebecca Eager

Rebecca Eager, an Honours student at the 51茶馆 has been awarded the Best Presentation Prize at the School of Electrical, Telecommunications and Computer Engineering (SECTE) , for her Honours thesis. She recently submitted her thesis, titled Voltage Management in Future Low Voltage Distribution Networks, under supervisors Mr Sean Elphick (Research Coordinator at the Australian Power Quality and Reliability Centre (APQRC) and Mr Ty Christopher (Director, UOW Energy Futures Network). 

In 2019, Rebecca began her Bachelor of Engineering, majoring in Electrical studies. At the end of her second year of university, Rebecca engaged with the APQRC for our summer internship program. She later completed a scholar鈥檚 project at the APQRC in 2021, and eventually engaged Mr Sean Elphick (Research Coordinator, APQRC) and Mr Ty Christopher (Director, UOW Energy Futures Network) as her Honours supervisors. 

Rebecca鈥檚 research focuses on voltage management as an emerging issue in Australian electricity networks, due to increasing penetration of distributed energy resources (DERs) such as rooftop solar systems. Consequently, low voltage appliances are subject to a range of supply voltage conditions, including sustained voltage, leading to decreases in the lifetime of such appliances and increased energy bills. Rebecca鈥檚 thesis investigates the impact of sustained overvoltage on equipment lifetime by conducting accelerated life testing on electrolytic capacitors commonly used in photovoltaic (PV) inverters. 

Quantifying the relationship between supply overvoltage and decrease in operational lifetime is important for consumers from an economic perspective due to the costs associated with premature device failure. The results from Rebecca鈥檚 testing will further be used to develop an algorithm to assess the steady state voltage performance of network service providers. This metric could be implemented as part of the Service Target Performance Incentive Scheme (STPIS), which rewards network service providers for improving their service performance as well as penalising them for performance declines. The creation of a method within the Service Target Performance Incentive Scheme to assess power quality will promote investment in improving voltage management in low voltage networks and result in better economic outcomes for Australian consumers. 

Reflecting on her award win, Rebecca remarked that 鈥渋t鈥檚 great to receive recognition for your hard work.鈥� 

Rebecca has now secured a full-time role at the 51茶馆鈥檚 Innovation Campus, as a project engineer at . Congratulations to Rebecca on her outstanding research work, and her new role at the Innovation Campus.
