Transient modeling of photovoltaic system (PV) to investigating the peak of transient voltage generated by direct and indirect lightning strikes

Nowadays, to having greater protection of the environment and due to the pollution caused by using fossil fuels and the limitation of these resources, the global orientation towards is renewable energy sources. As a sustainable form of energy, solar energy is really important, because that is almost the cheapest source of energy production in areas with high solar radiation potential; so global demanding of electricity generation can be supplied with using this technology. There is possibility of direct or indirect lightning strike on photovoltaic system equipment due to the installation of this equipment outdoors or on rooftops. In this paper, the transient overvoltage crated by direct and indirect lightning strike to the photovoltaic frame in different parts of the photovoltaic system is investigated by an accurate modeling of the frame, pillars and ground of a photovoltaic system in EMTP-RV.
