The importance of PV penetration in power system as a major element of renewable energy source has seen it being widely used on a global scale. Despite its promising success, PV penetration presents various issues and its impact on the distribution system has to address for seamless integration in the power 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.
Additionally, high PV penetration can also lead to increased power losses and reduced system stability, requiring advanced grid management techniques and infrastructure upgrades. Singh et al.
