Abstract :
In this paper, we mainly study the impacts of a small photovoltaic power station on voltage sag. Firstly, simulation model of photovoltaic power station is made in PSCAD. Secondly, we make the fault probability model of voltage sag based on Monte-Carlo method, and analyze two kinds of cases on grid-connected PV system: the same capacity in different location and the same location with different capacity. Comparing to system without PV, the capacity and grid-connected location would affect voltage sag frequency, and it provides a reference for the research on Grid-connected PV system.
