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.

The severity of these issues depends on the penetration level of PV, configuration of distribution system and the location of PV in distribution system. In such cases, high level of PV penetration can inject power to transmission network which can affect the voltage level and protection setting of the distribution system.
