A Systematic State of Charge based V2G Charging Framework for Frequency Response

As the demand fluctuations are very high, attaining equilibria of power in a grid is a challenging task due to the fluctuations in frequency. Hence, a novel scheme has been proposed which responds to frequency change in the grid using plug-in electric vehicles (PEVs) owing to their high performance battery characteristics and longer plug-in time. In this paper, a systematic framework for vehicle-to-grid (V2G) control has been proposed to limit the charging/discharging of battery with respect to the end user convenience for participating in the frequency response within a range of battery state of charge (SoC) limit.
