Enhancing voltage stability index after adding EVs charging station by using PV system

Abstract

     This research paper presents a comprehensive study of a modular system that has previously hosted electric vehicle charging stations. This research focuses on addressing the impact of incorporating these chargers through renewable energy sources, given their role in mitigating global warming and reducing dependence on conventional energy sources. Therefore, photovoltaic energy systems were used and integrated into a modular system using the ETAP program, after adding five charger stations at different power levels, which led to the voltage stability index dropping to less than 90%. An integrated photovoltaic system was modeled and added to the IEEE 30 Bus standards, incorporating chargers. Voltage stability analyses were conducted for both voltage analysis types in the sensitivity analysis and P-V and Q-V analyses. Detailed results were obtained, the most important of which was that the voltage stability index of the weakest conductors reached more than 95% after adding PV station, which is explained in detail in this paper.
