Abstract

In this paper, the simulation model for grid-integrated PV station is established in DIgSILENT/ PowerFactory. The impact on reactive power and voltage of the grid are investigated for integration of PV station. The principle that PV station affects the voltage of the point of common coupling (PCC) is analyzed. Taking a PV station integration project as an example, this paper discusses the operation characteristic of the PV station when it works as a current-source, and presents technical solutions to improve the static voltage stability of system.
