Review of Active Power Measuring Methods for Vehicle-To-Grid (V2G)

The modeling and measuring methods for V2G are reviewed. First, the concepts and the urgent problems of V2G are introduced. Then, the charging and discharging models of vehicle in power grid are analyzed. All of them cannot be used in active power measurement because they are established based on sinusoidal theory. Third, measuring methods of active power for V2G in recent years are summarized which are focus on the charging states. Finally, charge-discharge model of vehicles for V2G is established and the corresponding measuring method of active power is presented.
