The PhD project will investigate the topics of secondary and renewable heat and cold utilisation for low temperature urban energy networks. In addition, flexible electricity supply, electric vehicles, demand side management and energy storage for integrated smart energy systems will also be investigated. Our project will investigate the feasibility of a novel urban smart energy system in London to connect flexible electricity demands such as heat pumps and electric vehicles to the intermittent renewable resources such as wind and solar power, combined with secondary heat sources, energy storage and smart grid control. The aim is to investigate and develop a novel sustainable smart energy system capable of delivering low carbon low cost energy. The project is in conjunction with Islington Council and builds upon previous demonstration and modelling studies of secondary heat use within Islington Council’s energy network.
