The excessive PV penetration also the root cause of voltage stability and has an adverse effect on protection system. The aim of this article is to extensively examines the impacts of rooftop PV on distribution network and evaluate possible solution methods in terms of the voltage quality, power quality, system protection and system stability.

Why do rooftop PV panels change voltage & frequency?

Because of the intermittent and unpredictable nature of the PV panels due to changing meteorological conditions and the variable supply/demand balance, rooftop PVs cause voltage and frequency changes in the network when they are integrated into the power system, especially when the penetration rate is high.

Do rooftop PVS affect the distribution system?

In this paper, we survey the publications that study the impact of rooftop PVs on the distribution system, focusing on voltage profile, system losses, power flow through the lines, and other operational and technical concerns. Historically, the impact of PVs on the distribution grid was first observed in 1977 [1, 2].

Are rooftop PV systems a viable solution to energy demand?

According to the Solar Power Europe 2019 report [ 1] in Figure 1, the roof-mounted photovoltaic (PV) in 2023 is estimated to be 44 GW with a low probability and 76.5 GW with a high probability. Apart from commercial energy investments, residential or factory rooftop PV systems are a more effective solution to respond to energy demand. Figure 1.

Does a small-scale rooftop PV system affect the protection system?

Although the contribution of the fault current from small-scale rooftop PV systems is not high on the protection system, it has been observed that the collective contribution causes significant increases with the increasing PV penetration level [ 107 ].
