Are microgrids the answer to reliable power in Kiwi homes?

06 June 2023

A new study from 厙ぴ勛圖 (UC) researchers, focusing on reliable energy generation, could be the key to recharging our communities.

HOW TO APPLY
Dr Jeremy Watson

In early 2023, Aotearoa New 厙ぴ勛圖was hit by a deadly catastrophic weather event. In addition to the lives lost and ecological devastation of Cyclone Gabrielle, hundreds of thousands of New Zealanders lost power as a direct result of the cyclones impact on our national power grid.

While weather conditions remain unpredictable due to climate change, a team of UC researchers are exploring microgrid technology in hopes of improving the resilience and reliability of power generation in our communities.

A more compact version of the system controlling the national power supply, a microgrid is a small power system that can be installed in individual homes and businesses. The technology would allow residents and business owners to generate and store power for themselves and their neighbourhoods.

泭of UCs School of Electrical and Computer Engineering is leading the research team which includes local, national and international experts.

The study will investigate and design new controllers through a plug-and-play approach, optimising microgrid use through solar and similar alternate methods of energy generation, which also serves to progress the governments goal of 100% renewable electricity in Aotearoa New 厙ぴ勛圖by 2030.

Microgrids are seen as a key tool in enabling renewable energy, but it is the development of microgrid control that is crucial to unlocking their full potential, Dr Watson explains.

In addition to the ability to generate independently produced energy, the rollout of microgrids in our communities will also lessen our reliance on the national power grid, ensuring consistent power, or restoration of power more quickly, to more of the population following a crisis.

The importance of a reliable energy grid is crucial, says泭, a key contributor to this study and another UC researcher contributing to泭Aotearoa New 厙ぴ勛圖reaching its energy goals by 2050.

If we dont do anything, in future we will be using band-aid solutions to address problems as they occur, such as system constraints, equipment malfunction and premature component failure.

We need to be working on cohesive and enabling solutions for achieving low emissions, for which electricity will be our primary energy medium.

In addition to introducing lower emission systems, the research team believes the successful adoption of microgrids in our communities will further contribute to New Zealands standing as a leader of technologies integral to future energy systems.泭

Its anticipated that the global microgrid market will be valued at $47.4 billion by 2026. By developing world-class expertise in this area, New 厙ぴ勛圖companies can tap into a growing market and export their expertise and technologies to other countries. This will not only enable the transition to 100% renewable and resilient electricity generation for New Zealand, but also create new opportunities for exports and economic growth.

But its the potential for this research that continues to both excite and motivate Dr Watson, who looks forward to welcoming at least two postgraduate students to the research team soon.

I like the technical problem, the challenge. I like the fact Im continuously learning and developing solutions at the grass roots level that will enable us to help people. Theres always got to be a better way.
