A smart MV/LV-station that improves power quality, reliability and substation load profile

Abstract

Because of the increasing penetration o f dispersed generation and developments in the power demand, the power flows in LV and MV distribution grids will increasingly fluctuate in the near future.To manage these fluctuations while maintaining power quality and reliability, a Smart MV/LV-station has been designed by a Dutch consortium.A prototype of this station will be built and tested.Tests will take place both in the Flex Power Grid Lab in Arnhem (NL) and in a live test grid of the Dutch grid operator Liander.Results of the lab test and the live grid demonstration are expected during 2009 and 2010.First simulation results show a significant reduction of harmonic voltages and resonances, as well as a peak load reduction of 30%.
