ABSTRACT: In this paper, the fundamental structure of charge and
discharge device of V2G is
analyzed. As for three phase voltage source PWM converter’s control, this paper
presents that the control strategy of direct power control PWM rectifier is
adopted under charging operation and constant power control strategy is used
under discharging operation. For bidirectional DC/DC converter control
strategy, dual closed-loop control of external voltage loop and internal
current loop is put into use. The whole system of charge and discharge device
of V2G is modeled and simulated by
using the toolbox of PSCAD/EMTDC. Two-way power energy and information
interaction of electric vehicle and power grid has been realized, current
harmonic on grid side is decreased, power factor and power quality are
improved.
