Journal ArticleDOI
Coordinated Active Power Curtailment of Grid Connected PV Inverters for Overvoltage Prevention
TL;DR: In this paper, the authors discuss the use of droop-based active power curtailment techniques for overvoltage prevention in radial LV feeders as a means for increasing the installed PV capacity and energy yield.
Journal ArticleDOI
Impact of High PV Penetration on Voltage Profiles in Residential Neighborhoods
TL;DR: In this paper, a simulation study was performed to investigate potential voltage rise issues in the network up to 11.25% total PV penetration in the feeder and LV transformer capacity penetration up to 75%.
Journal ArticleDOI
