Coordinated Charging Strategy for Electric Vehicles in Temporal-spatial    Dimension Based on IBQPSO Algorithm

The disorderly charging of large-scale electric vehicles will affect the safe and economic operation of the power grid. The charging behavior of electric vehicles needs to be guided by the cost compensated by the charging station operator according to contribution of user’s guided charging behavior in temporal and spatial levels to the grid scheduling. Based on this, a temporal-spatial charging guidance model is established. Then, an IBQPSO algorithm is proposed based on Bloch sphere to solve the model. Finally, the simulated results of a specific example show that the interests of the grid, charging station operators and electric vehicle users can be meet, and the feasibility and effectiveness of the model and algorithm are verified.
