Abstract :
DC electricity systems are making a comeback. Not as a competitor to AC but as a partner, where DC offers advantages which AC cannot match.DC has advantages where distances are small, where DC loads dominate, where DC generation is included and where storage is involved. Project Edison - the DC library is a smart DC micro-grid powering part of the library at the University of Bath. The principal load is a suite of computers, providing 24 hour - 365 day service for study and research. It also supplies priority LED lighting. Using battery storage, security of supply is enhanced, power system distortion is constrained and there are opportunities for time-of-use management.
