The invention relates to an electric vehicle charging and discharging station energy control system and a control method thereof.The system comprises a charging and discharging unit, an alternating current bus, a public network unit and a monitoring and service unit. If the capacity of the transformer is insufficient and the load of the line is continuously increased, the vehicle connected with the V2G charging pile can be used as an energy storage unit to discharge in real time through the authorization of a vehicle owner and the matching of a vehicle-pile-background process, reverse alternating current electric energy is provided for an alternating current bus within a set SOC, and in-station recycling of energy is realized; and the circuit burden of the power system is effectively relieved.
