| Abstract: | Based on the vehicle to grid (V2G) system, an optimal analysis model which can be used to adjust the power distribution networks load is investigated in this paper. Firstly, the control system of the load regulation with V2G is designed. Considering the users' charging demand, the charging power constraint of power battery and the power constraint of transmission lines, an optimal analysis model is established by taking the load curve of fluctuation variance of power distribution networks as the objective function. Finally, genetic algorithms is used to calculate best charging and discharging time for electric vehicles, as well as the optimized load curve. Through an example simulation, the effectiveness of the optimal control method is verified. |
