Investigation on Voltage Control in Large-scaled Grid-connected of Photovoltaic Station
Abstract:The large integration of the photovoltaic power generation systems can deteriorate the safe and stable operation of power systems, especially the short-term voltage stability. In this paper, a 3-node system model for short-term voltage stability analysis of photovoltaic grid-connected is established. The effects of different factors such as photovoltaic permeability, dynamic load ratio, grid strength and inverter control strategy on the short-term voltage stability of the system are analyzed, which provide ideas for further voltage-friendly control strategies.
Keywords: PV generation system LVRT process Short-term voltage stability Voltage instability Voltage-friendly control
