The invention relates to an energy internet oriented AC/DC hybrid microgrid coordination optimization control method and system, and belongs to the technical field of the energy internet and microgrids. The system comprises a plurality of sub microgrids, each sub microgrid consists of two interface converters which are connected with an alternating current bus and a direct current bus, the first interface converter adopts a current control closed loop, the second interface converter adopts a voltage control closed loop based on self-adaptive virtual impedance, and the power deviation of the two interface converters is used as an adaptive setting reference of the virtual impedance of the second interface converter. The first interface converter adopts the strategy of combining the power outer loop control and current outer loop control strategy and the current inner loop control strategy, the second interface converter adopts the strategy of combining the droop control outer loop and the voltage control strategy based on the self-adaptive virtual impedance and the current inner loop control strategy, by coordinated control of the adaptive virtual impedance, the performance of the AC/DC hybrid microgrid is improved.
