Popis: The penetration rate of Wind-Soloar-Storage integrated grid-connected systems in the power grid is getting higher and higher. However, the mechanism of its influence on the short-circuit current is still not deeply understood. This paper analyzes the low-voltage ride-through and reactive power compensation strategies of a Wind-PV-Storage integrated grid-connected system; the short-circuit process of the AC side is studied, and the voltage sag degree and limiting link affect the steady amplitude and phase of the current. Through establishing the Wind-PV-Storage integrated grid connected system model in PSCAD/EMTDC, theoretical analysis and verification are carried out on the influence of factors such as the collection line inside the station and different capacity distribution proportions of the station on the short-circuit current.
