Abstract: Large solar photovoltaic (PV) penetration using inverters in low-voltage (LV) distribution networks may pose several challenges, such as reverse power flow and voltage rise situations. These challenges will eventually force grid operators to carry out grid reinforcement to ensure continued safe and reliable operations.
In this work, a control scheme for PV inverters is proposed toact during faults that could compromise the transient and voltagestability of a hybrid power system.
