The invention discloses a method and a system for realizing ordered charging through alternating current and direct current integrated control. The method comprises the following steps: a charging cloud platform issues a total power limit value to an alternating current and direct current charging system; in the alternating current and direct current system, a direct current controller receives a total power limit value issued by a charging cloud platform, and a power value corresponding to direct current equipment is obtained through a power limit value calculation algorithm; limiting the output power of the direct current equipment according to the obtained direct current power limit; the alternating current power limit of each alternating current device is sent to the corresponding alternating current controller, the alternating current controller receives the alternating current power limit issued by the direct current controller, and the alternating current controller achieves the function of regulating
