V2G for Power Distribution Line Stabilization

The ‘Vehicle to Grid (V2G)’ has been known as the key technology combining both electric power and transportation industries. V2G concept in this paper contains both ‘Smart Charging (SC)’ and ‘Reverse Power Transfer (RPT)’ initiated by Demand Response (DR) signal from power utility, to stabilize Power Grid. Since the national power demand-supply balance is very stable in Korea, our research has been focused on EV charging/discharging technology for stabilizing ‘local’ power load on each Distribution Lines (DL). The SC and RPT with real V2G EV, DL power load prediction, and power control simulation will be presented in the paper.
