Revenue valuation of aggregated electric vehicles participating in V2G power service

Abstract

The capability of electric vehicles (EV) to store grid energy has created avenues to utilize them for grid services through controlled bidirectional power transfer known as vehicle-to-grid (V2G) system. The study presented in this paper valuates the potential revenue that could be drawn by providing V2G power service under varying penetration of aggregated vehicles. The determination of saleable component for V2G supply involves integration of critical mobility attributes to model the energy consumption in driving. Time-of-use pricing differentiating between on-peak, off-peak and mid-peak periods has been utilized along varied discharge power levels of existing charging standards to compute the total revenue share. Results established that the plug-in hybrid electric vehicle (PHEV) and battery electric vehicle (BEV) compositions in the system along with discharge power rate regulates the return on V2G power service. The dividend on the part of grid service would be a motivation for their greater adoption in the view of their expensiveness in present state. © 2015 IEEE.
