Global Innovation Linkages Workshop, 11 November 2022
APQRC Director, Duane Robinson and Research Coordinator, Sean Elphick were joined by PhD students Imanka Ranmanna Dewayalage and Kasun Peiris at the Global Linkages Workshop 2022. The workshop was held in Hobart on 10-11 November 2022.
The APQRC team presented an update on our 4-Year project titled Power Quality of Future Electricity Networks. Penetration levels of new energy sources including solar, and wind are on the rise in electricity grids across the world. These sources are connected to the grid through power electronics-based interfaces leading to new challenges surrounding the generation of unwanted harmonics. These harmonics can impact the grid and have become a concern to all stakeholders as their levels have to be managed below stipulated limits to ensure power system security. The project addresses these concerns and involves the measurement and assessment of harmonics and their impact on connected equipment. Such projects are crucial where there are deficiencies in the existing technologies and knowledge.
On Day 1, PhD Student Kasun Peiris presented an update on the progress of their UOW work package, which involves measurement and characterisation of the harmonic emission from renewable energy generators. On Day 2, we attended a technical tour of Cattle Hill Windfarm.
