Abstract

This paper aims to investigate the impact of installing photovoltaic distributed generations (PVDGs) in distribution systems. Detail model of PVDGs in current control mode are discussed. Dynamic responses during abnormal events (e.g., voltage sag and three-phase fault) are investigated. Impact on operation of protection devices are analyzed and depicted by two dimensional plots of R-X trajectory. Comparative analysis on installation of DG in distribution systems between PVDGs in current control mode and synchronous machine DGs are discussed. Conclusion can be drawn from simulations that fault current of PVDGs in current control mode is significantly lower than the synchronous machine DGs.
