State of the art electric drive vehicles are one of the most encouraging automobile technologies to reduce our dependence on expensive, polluting fossil fuel based conventional vehicles. However, arises a new fear: the grid anxiety — whether the existing power grid, as it stands right now, will be able to handle the additional load put up by these vehicles. In this work, actual transportation statistics, together with two possible charging schemes — constant time and constant power for two charging levels of 3.3 and 6.6 kW, have been used to obtain the load profile of electric vehicles. The augmented charging load of electric vehicles may also affect the behavior of electricity market due to increase in total load. This paper analyzes the impact of vehicle's load on electricity market price in a day ahead market model. The constant time charging along with low charging power comes out to be an optimal scenario, when tested on a modified IEEE 30-Bus system.
