Technical Impact of PV Distributed Generation on Arc Flash Hazard in Egypt Low Voltage Distribution Networks

Egypt faces a significant challenge in giving an adequate amount of electrical from its primary sources of energy, particularly oil and gaseous petrol that represents 95% of the total energy resources required for producing power in Egypt. Subsequently, diversification of energy resources is needed to maximize the benefits of utilizing local resources which are described by stable costs and continuous such as investing in (PV-DG) photovoltaic generators are connected to the distribution systems of electricity, generated electricity from solar energy that are rich in Egypt. There is therefore an increasing need to recognize and measure the technical issues caused by (PV-DG) photovoltaic distributed generation systems, this paper aims to assess the impact of (PV-DG) on incident energy and arc-flash risk levels at low voltage level based method according to IEEE 1584-2018 guide for the estimation of the arc-flash risk and ETAP software. Followed by selecting appropriate settings for protective devices to achieve minimal incident energy.
