The electrification of transportation offers the broadest potential impact, both economically and in its positive environmental effects. Benefits of electric vehicles include no emissions, less noise pollution, and lower maintenance costs. The market for electric vehicle is presently limited in Pakistan but it is expected to increase rapidly in near future. As the number of Electric Vehicles (EVs) continues to rise, the power grid is encountering significant challenges due to the increased prevalence of EV charging stations. Therefore, a technical analysis of the impact of EV charging on the distribution system is required. This study uses the MATLAB/Simulink tool to analyze the Total Harmonic Distortion (THD) and power losses carried on by the integration of electric vehicle charging stations into the HESCO (WAPDA) power system. To determine the power losses and THD caused by EV charging stations at various locations of the distribution feeder, comparative studies on the feeder with and without EV charging stations are conducted.

Electric buses are increasingly appearing on the streets of cities around the world. Thus, it is necessary to consider the impact of their charging on the distribution system operation, especially near the charging point. This article presents the problems that may arise while new charging points are connected. Research was carried out on the existing charging point at Spartańska Street in Warsaw, which allowed to obtain daily bus charging profiles and voltage curves. The authors then proposed an exemplary model of a bus terminus with the designed infrastructure for charging buses, based on the assumptions of the public transport operator in Warsaw. The comparison of these two solutions was made and based on it, a methodology of calculating daily demand for any terminus was prepared. In addition, no problems with the power quality were found during the research. This allows us to state that the introduction of electric buses into the fleet of passenger carriers will have a minor impact on the operation of the power system in Warsaw.

“…According to research by [Jun, Y., Xuemei, L., et al 2019], It is concluded that the Electric Vehicle (EV) charging load increases the peak difference of the power grid and makes the power grid voltage drop seriously. According to research by [Andrii, B., Alla, B., et al 2019], It is concluded that the influence of the charger on the quality of electricity and it is found that the efficiency coefficient is about 55%. According to research by [Kevin G. H. et al 2019], the charging position of EVs on the grid significantly affects voltage drop conditions.…”

Public Electric Vehicle Charging Stations (SPKLUs) are critical infrastructure in facilitating the increasingly popular use of electric vehicles. The increasing number of electric vehicles using SPKLU also has an impact on existing transformers and distribution networks. This research uses the Fluke 1748 tool to analyze the impact on transformers and distribution networks. The Fluke 1748 is a tool that can record and analyze electrical parameters such as voltage, current, power, and power factor with high precision. The method used in this analysis involves installing the Fluke 1748 device at strategic points around the SPKLU, transformer, and distribution network. The results of this study are At the public electric vehicle charging station, an analysis has been carried out on the voltage and current where the results of THDV of 2.212% still meet the IEEE 2014 standard and THDi of 4.929% meet the IEEE 2014 standard, the impact caused is that there are losses in kWh sales due to voltage drops or voltage drops of 2250 watts, losses in significant transformers and in the conductor also cause a voltage drop of 2.5% of the nominal voltage.
