Voltage dependent load models of charging electric vehicles

Plug-in Electric Vehicle (PEV) integration on distribution grids is an important topic of research due to the potential problem involved. In order to accurately assess the impact of EVs on system voltages and power flows, accurate voltage dependent models must be used. In this work, the voltage response of four different EV types is measured and ZIP models are developed for each which can be used in EV integration studies. The measurements show that the behavior varies significantly between the different EVs and thus an accurate generic model cannot be made.
