Charging–discharging coordination between electric vehicles and the power grid is gaining interest as a de-carbonization tool and provider of ancillary services. In electric vehicle applications, the aggregator acts as the intelligent mediator between the power grid and the vehicle.
The mathematical model of the charger/discharger is obtained by studying the differential equations governing the converter for the two possible conditions of the control signal u, which are reported as follows: is ON. For this analysis the effect of both the leakage 2.2. Averaged Model
The charger/discharger must be designed to provide low-harmonic distortion to the DC bus; therefore, must be small, but depends on the transformer parameters. In addition, Equations ( 1) and ( 2) show that the derivatives of and have opposite signs, as consequence, the most negative value of occurs when has the most positive value.
The battery will only normally discharge when the energy meter senses power coming from the grid (and there is charge available in the battery). In the normal operation of electrical appliances, they will be switched on and off by the end user, or in the case of heating and cooling, a thermostat will control loads on and off.
The uncontrolled charging–discharging method is very simple and directly exposes the grid. In this method, the grid operator does not receive any user information about the system, which may result in problems with grid stability, power quality, operational efficiency, and battery state-of-charge (SOC).
