Abstract
Recent advancements in the development of electric vehicles (EVs) will lead to their rapid integration in the transportation sector of Bangladesh. Charging of EVs can be accomplished by either domestic slow charging or public fast-charging station. This study investigates the impact of fast charging stations (FCSs) on a middle-income, urban residential distribution network in Dhaka. Bus voltage profile and the total loss have been investigated using load flow analysis considering parameters such as specification and number of EVs, charging pattern of EVs, hourly load profile, and seasonal variation. Finally, the placement of the FCS has been varied to identify the effect of location on the voltage profile and power loss of the investigated network. Finally, the critical EV penetration level in the studied network has been investigated that can be deployed without making additional modifications to the existing grid. The effect of EV integration on distribution networks during summer is found to be more detrimental than in winter. The placement of the fast-charging station plays a crucial role in the voltage profile of the grid as well as in the power loss of the system. Nonetheless, a low level of EV penetration does not jeopardize the operation of the system.
