While the pollution is increasing resulting in green house gases and global warming, the amount of electric vehicle is predicted to increase. Most of the electric cars are design for urban use, and these vehicles need to be recharged in evening or during night, so the electric vehicles will interact with grid during this period. This process will impact the network voltage profiles and loading of grid elements. Existing Grids were designed several decades ago, so it becomes necessary to take a note of this that whether they will be able to support this increased loading, or is there a requirement of reconstruction to meet this demand. Most consumers will prefer charging during night time at their premises itself, which is LV system. And which operates at 230 V. So LV grid is taken in consideration to understand the impact of charging electric vehicles. As loads is connected to different phases, so there will be a phase asymmetry in the network. This asymmetry can be reduced by proper planning of the grid. Injection of electrical vehicle into the grid will also have an impact on power factor. As some consumers turn on or off their electric vehicles, the overall power factor changes. This has to be considered as this impact the reactive power consumption. With increase in the number of electric cars, the loading characteristics of transformer changes. For this work grid without electric vehicle and with electric vehicle is considered and Grid parameters are analysed.
