Deep changes are happening in the supply side of energy systems. China is adding about 20 GW of wind generation capacity per year and has replaced all buses in the city of Shenzhen with electric busses. The UK has halved carbon emissions from electricity system from over 150 million tonnes in 2012 to under 70 million tonnes in 2018. Very clearly there is much more to do: the remaining decarbonisation of electricity, the electrification of other sectors and sourcing alternative, zero-carbon fuels. The development of smart urban energy systems is the key to achieve green and low-carbon urban development and promote the decarbonisation and electrification of the energy supply. Nowadays urban distribution systems lack of power flow control devices, the characteristics of the system with large penetration of power electronics devices are unrevealed.
In order to address these, this project conducts the strong collaborated research works between five universities from both China and Britain, aiming to solve the challenging problems within the topic of Interactive Operation and Resilient Control to Support Power Electronics Based Smart Urban Energy Systems. It includes the key power conversion technology to enhance the flexibility of urban energy systems, operation strategies for power electronics based urban energy systems, decentralised real-time control for intelligent and resilient urban energy systems, and resilience and fault management in a power electronics dominated environment. The main innovation of this project includes: development of topology and control strategy for multi-material-devices based power electronic converters for urban systems, operation strategy for smart urban energy system considering massive power electronic converters and multi-energy system, self-stabilizable and self-adaptable control of power electronic converters in urban systems, and data-driven based fault detection and self-healing method for power electronic converters in urban systems.
Despite the differences between the histories and geographies of cities in China and the UK, we find common challenges and a complementary set of research expertise. This project brings together experts in power electronics, optimization, control and fault-management from UK and China. Following the research activities, both Chinese and British parties will build deeper collaboration in this area and provide theories and solutions to further support the development of urban energy systems.
