Local Control of Reactive Power by Distributed Photovoltaic Generators [PDF]

2010 First IEEE International Conference on Smart Grid Communications, 2010
High penetration levels of distributed photovoltaic (PV) generation on an electrical distribution circuit may severely degrade power quality due to voltage sags and swells caused by rapidly varying PV generation during cloud transients coupled with the slow response of existing utility compensation and regulation equipment. Although not permitted under
