Modeling and studying of power flow in a parking lot with plug-in vehicles and the impact in the public utility

For a massive introduction of electric vehicles to the market is required to have a reliable infrastructure. The Infrastructure needs includes enough charging stations around cities and electric parking lots. Currently the grid is able to support the electric consumption and hardly support recharging the fleet of electric vehicles. Likewise, the public utility has to keep high power quality without blackout, voltage dips, harmonics, etc. This paper studies the electric infrastructure of an electric parking lot. It is considered a high penetration of charging stations. The analysis has been performed by means of vehicle battery and charging station modeling in MATLAB Simulink. The paper analyzes the power flow into the distributed transformer using three different scenarios.
