CIGRE UK NGN Young Member Showcase - finalists presentations & judging

About this event

The CIGRE UK NGN Young Member presentation competition provides an opportunity for early career electrical engineers to showcase their work to the wider CIGRE community. A panel of senior CIGRE members will judge which participants will be put forward to present at the 2022 CIGRE Session.

Delegates will gain insight into the exciting projects that the next generation of electrical engineers are working on and will have the opportunity to ask questions during the Q&A to find out more. As a delegate, you may also learn a thing or two about what makes presentations engaging and how to best adapt to the online format. So come along and show your support!

Bubble Formation in Power Transformers – a Potential Risk for the Future Network Reliability

This paper introduces the development of a small-scale test setup along with a testing procedure to investigate the bubble formation of transformer insulation systems. The system design and test procedure has been verified through multiple studies on the temperature and water content in the system. Furthermore, initial tests have confirmed that results are in line with literature and the system is suitable to perform a coherent study on the impact of various parameters such as the temperature rise, material type or condition. Those results will help to answer the question if bubble formation is a potential risk for power transformers under future energy scenarios.

Enhancing the Green Hydrogen Business Case

Two business cases are examined aiming at facilitating the deployment of grid-connected onshore wind farms. Specifically, onshore wind farms are assumed to be co-located with electrolysers and it is examined if the presence of energy storage units can improve the load factor of the electrolyser, and therefore the green hydrogen (H2) business case, under three different pre-agreed fixed hydrogen prices.

Modified ON-OFF Control for Very High Frequency Class E DC-DC Converter with Efficiency Improvement

Very high frequency (VHF, 30 MHz-300 MHz) Class E dc-dc converter is widely used in low power conversion applications, in which constant switching frequency (CSF) ON-OFF control is usually adopted to regulate the output with the advantages of simple implementation and full-load-range ZVS realization. However, it is found that the conversion efficiency greatly reduces with the rise of input voltage in CSF ON-OFF control. In this paper, two modified control schemes are proposed to improve the conversion efficiency of VHF Class E dc-dc converter at high input voltage range and over the entire load range, respectively. The proposed control schemes are free of extra hardware cost and can be implemented easily. Experimental results are shown to validate the effectiveness of the two modified control schemes.
