Influence Factors Analysis and Modeling of Power Demand for Electric Bus Charging Station

With the Large scale operation of the electric bus, the growing charging power demand will have certain influence on power grid. The arriving time and initial energy state of electric bus influenced by such factors as traffic, car speed and busload are analyzed firstly. Then the power demand model for electric bus charging station is built according to initial energy state, start charging time and real battery charging power curve. By using of proposed model, the charging power curve within a day for electric bus charging station is obtained based on the operating data in a demonstration electric bus charging station and the calculation model of initial energy state and the arriving time. The comparing between calculation results and real charging station verifies the validity of proposed model.
