Power Electronics, Machines and Power System (PEMPS) Group

The Power Electronics, Machines and Power System (PEMPS) Group is an expanding research group at Aston University which undertakes research into both theoretical and practical aspects of power electronics and its impact on electrical power networks, ranging from the analysis and management of hierarchical complex networks such as a power electronic system, through to hands-on industrial experience in distribution and transmission networks. The group has extensive links to industry and undertakes undergraduate teaching (primarily foundation degree) to major Power Utilities.  

The electricity industry is undergoing significant changes to evolve into the “smart” grid of the future. The Power Engineering and Power Electronics group at Aston believe that the key to many of the changes that lie ahead will involve power electronic solutions (also including electronic breakers, fault-current limiters). These changes include but are not limited to bi-directional energy flow, increased demand (due to increased transport electrification), hybrid ac and dc networks and the integration of different energy storage media along with demand side management which will all require intelligent control and communications. These changes are not limited to traditional distribution and transmission networks but include all electrical networks including those around aerospace and other transport media.
