Energy Systems and Advanced Materials Research GroupThe Energy Systems Group combines two main areas of strength, photovoltaic and power engineering, with a view to addressing a field of growing importance, that of energy generation and supply. The Northumbria Photovoltaics Applications Centre (NPAC) carries out research on solar cell development, design and performance of photovoltaic systems and environmental impact analysis of this renewable energy technology. The Energy Systems Group also has expertise in wind power, particularly relating to control and generation aspects. The Power Engineering group undertakes research activities in emerging technologies in electrical power, including flexible AC transmission systems, custom power technology, quality of supply, embedded generation and variable speed motor drive systems. The research activities are strongly linked to industry requirements, with some having strong interdisciplinary aspects.
