The present invention provides a method and a device for inhibition of resonance between end-to-end MMC-HVDC (Modular Multilevel Converter based High Voltage Direct Current Transmission) direct current side stations. The method comprises the steps of: extracting a direct current fluctuation component from a direct current, and determining a resistance value of a virtual resistor introduced at an MMC-HVDC direct current side; determining a voltage drop component of the virtual resistor according to the extracted direct current fluctuation component and the resistance value of the virtual resistor; and determining an MMC bridge arm reference voltage after the virtual resistor is introduced according to the voltage drop component of the virtual resistor. The method and the device can inhibitgeneration of current resonance at the MMC-HVDC direct current side in a condition without extra loss and can reduce the possibility of generation of faults at the MMC-HVDC direct current side to improve the utilization efficiency of a voltage source converter and save the cost; the equivalent position of the virtual resistor is located on the bridge arm to have an inhibition effect on the resonance in the station; and moreover, the method is mainly achieved through improvement of the upper layer control of the MMC and is easy to implement.
