An economic model for power exchange of V2Gs in parking lots

Each battery vehicle (V2G) can be charged from the power grid or return its stored energy back to the grid. The effect of a single V2G on the power grid is approximately an ignorable noise. Parking lots can cumulate hundreds of V2Gs in a way that their load/generation impact can influence the grid. This paper proposes a technical and economic model for managing the charging and discharging time of battery vehicles in a parking lot. This model is employed maximizes the parking lot profit, while satisfying vehicle owners. The Genetic Algorithm (GA) is used to set the charging & discharging time table of vehicles. Finally, profit fluctuations due to varying the V2G parameters are investigated.
