Smart grids and integration 

Large scale integration of renewable distributed generation into the power grid has significant potential to both reduce carbon dioxide emissions and provide secure and resilient power. The current UK grid is largely a one way system with power generated in large power stations and distributed through transmission and distribution lines, with no storage capability.

The current system requires power generators to provide excess generation capacity to meet peak demands. The alternative is to develop smart grid systems which integrate power generation and storage through an intelligent communication system. 

The Power and Control Group at the University of Birmingham is involved in a wide range of research activity including:

  • Technologies for smart grids 
  • Application of power electronics such as FACTS (Flexible AC Transmission System) and
  • HVDC in transmission and distribution systems
  • Integration of PHEVs into power grids
  • Super AC/DC power grids for large scale renewable energy delivery
  • Protection and control of distribution networks with distributed generation
  • Micro-generation and Micro-grid
  • Smart metering and wide area monitoring and awareness
  • Power system economics 
  • Large scale power system optimisation and planning
  • Analysis and control of power system stability
  • Power quality and harmonics

Facilities

The University of Birmingham has advanced and unique facilities funded by Advantage West Midlands (AWM) and the European Regional Development Fund (ERDF) as part of the Birmingham Science City initiative - are being used to further the understanding of the operation, control and management of smart grid systems powered by energy from distributed sources. 

The facilities include two labs:

  • Real-time Power Grid Simulation, measurements, Control and Protection Lab.
  • Smart Power Grid Lab
