With the seriousness of environmental problems, people begin to use electric vehicles(EVs) instead of traditional vehicles, which can reduce carbon dioxide emissions. But a large number of electric vehicles plug-in grid will arise overload, voltage deviation issue, harmonic distortion, etc. which affect the regular operation of the power grid. Seriously, it may cause blackouts in the entire power grid. Therefore, it is essential for real-time detection of grid operation safety. In this paper, we propose a sensitivity analysis of active power and voltage at the same time to identify the impact of electric vehicle charging on the different load profile. The simulation results strongly suggest that when the EV penetration rate at a specific value, it will increase the deviation of active power and voltage and influence the electricity utilisation by users. Based on these results, we can specifically recommend them about the management of charging strategic of EVs.
