Abstract
Conventionally, voltage control in distribution grids has been achieved through load tap changers, capacitor banks, and network switches. With the advancements in on-board electric vehicle (EV) chargers, voltage control can be achieved through control of EV charging/discharging as EVs can operate in any of the four P-Q quadrants with slight modifications to the charger. In this work, we use a high-fidelity on-board EV charger model, which has been validated using actual measurements. Then, we coordinate the four quadrant operation of EVs and distribution feeder to support voltage control in the grid. The efficacy of the developed models are demonstrated by using an LV secondary feeder. Operation of EVs in all four quadrants are shown to compensate for the feeder voltage fluctuations caused by daily time varying residential loads, while satisfying operational constraints of the feeder.
