It is also a time of unprecedented challenges in power networks as we seek to integrate low carbon technologies: notably off-shore wind farms, photovoltaic panels and electric vehicles. A re-think is needed of many long accepted practices, such as how risk is managed and how resilience is provided in networks. Work is also needed on system-wide optimisation tools to support planning and design and on equipment design. Our main focus for equipment is the use of power electronics, spanning gigawatt scale power converters for offshore High Voltage DC, power converters for voltage control in local distribution networks and wireless power transfer devices for electric vehicle charging. Our theoretical work is tested and verified through a set of lab-scale prototype power converters and example network layouts in the Maurice Hancock Smart Energy Lab.
