Harnessing nature's power
Master of Engineering graduate Roomana Kalid is passionate about sustainable power solutions.
Roomana’s Master’s research explored the potential of solar panels and wind turbines as sources of renewable energy. She focused on optimising microgrids, which involved electrifying communities using these sustainable resources. The aim was to size the microgrid and ensure its feasibility while promoting sustainability and zero-carbon emissions.
Her research focused on two communities on Aotea Great Barrier Island. These communities are off-the-grid and individual households and businesses are self-reliant in terms of supplying their energy needs—mostly from fuel generators for electricity. Microgrids enable the communities to collectively supply their electricity needs more cost-effectively utilising renewable resources.
Roomana’s research demonstrates the techno-economic feasibility of such microgrids and the associated benefits. It paves the way for other communities to consider similar tailored systems to improve their resilience. Not only remote, off-the-grid communities, but also farmers that can use their land, water, and biomass resources more efficiently to improve their overall productivity and self-sufficiency, and urban communities with peer-to-peer energy trading opportunities that reduce bills and guard against extreme events, such as earthquakes and cyclones, that potentially disrupt infrastructure.
Roomana's interest in renewable energy was ignited when she contemplated the possibility of harnessing natural resources to power homes without relying on utilities—the national grid and local lines companies.
“Imagine electrifying your house with natural energy sources, such as the sun and wind, without paying any bills. Renewable energy is a more sustainable and realistic technology in this era. You can not only power your appliances with these resources but also store excess power in battery storage devices to utilise it later.”
Grateful for the guidance and encouragement she received at Te Herenga Waka—Victoria University of Wellington, Roomana cherished the support of her supervisor and colleagues. The open lines of communication fostered a responsive and helpful atmosphere, contributing to her growth and the acquisition of invaluable skills.
“I have met students with different cultural backgrounds, which fascinates me. My friends, supervisors, and colleagues are very supportive, and I have learnt a lot from them. I have enjoyed the whole research period, where I gained insight into different perspectives and acquired new skills. Doing my thesis is one of the best decisions I have made in my life.”
Roomana acknowledges that traditionally engineering was perceived as a male-centric field. However, times have changed, and women are now empowered to pursue any career path they desire.
“Engineering is a blend of scientific and mathematical knowledge with a deep understanding of technology's past and present. By keenly observing the world around you, anyone who is an aspiring engineer can contribute their unique ideas towards achieving remarkable innovations. The field of engineering harnesses creativity and offers abundant opportunities for professional growth.”
Looking towards the future, Roomana aims to carve a career path in the field of renewable energy and engineering.
“My goal for the future is to contribute to the creation of a better world for future generations, where renewable energy would play a pivotal role in establishing a sustainable and eco-friendly society.”
