The invention provides a charging station, a charging system and a control method thereof. In the control method, at least one of a power grid system, a new energy power generation system and an energy storage system is controlled to supply power to a charging system according to the magnitude relationship between the total charging demand and the maximum output power of the power grid system, the grid-connected power of the new energy power generation system and the maximum discharging power of the energy storage system; therefore, in the charging peak period, power is not supplied to the charging system only by the power grid system any more, but power is supplied to the charging system by at least one of the new energy power generation system and the energy storage system and the power grid system together, so that the total charging demand in the charging peak period can be met; therefore, the control method can reduce the limitation possibility of the charging power of the charging pile in the charging peak period.
本申请提供一种充电站以及充电系统及其控制方法。在该控制方法中,由于根据充电总需求与电网系统的最大输出功率、新能源发电系统的并网功率以及储能系统的最大放电功率之间的大小关系,控制电网系统、新能源发电系统、储能系统中的至少一个向充电系统供电,所以在充电高峰时期时,可能不再仅由电网系统向充电系统供电,而是可能由新能源发电系统、储能系统中的至少一个以及电网系统共同向充电系统供电,从而可能满足充电高峰期时的充电总需求,因此该控制方法可以降低充电桩的充电功率在充电高峰期时的受限可能性。
