Abstract/Summary Due to the increased concern of global warming, solar energy based Photovoltaic (PV) generation schemes are gradually becoming more popular as an alternative renewable energy source. As PV units may be located closer to load centers than traditional power plants, they can aid in improving the reliability of the network. Despite these environmental and technical benefits, the dynamic voltage behavior of a power system under the influence of large-scale PV units needs to be investigated for potential upgrade of existing standards. This research paper presents analyses of the impact of large-scale PV on dynamic voltage stability with respect to short and long term state variables for IEEE 14 bus system. Preliminary findings suggest that the influence of large-scale PV depends on PV controller type and setting. It is also noted that the integration of large-scale PV has implications on dynamic behavior which are not adequately captured by static analysis alone.
