description The invention discloses a transient stability control method of a direct current receiving end system and a related device, and the method comprises the steps: building a dynamic energy function corresponding to the direct current receiving end system based on the system parameters of a faulted direct current receiving end system; based on the dynamic energy function, determining a target dynamic energy gradient expression of the direct current receiving end system when a fault occurs; in the target dynamic energy gradient expression, extracting a function item related to an inverter side controller; and controlling parameters in the function term, so that the dynamic energy gradient of a direct current port corresponding to the direct current receiving end system is kept at a minimum value. The technical problems that when an existing direct-current receiving end system has a serious alternating-current fault, continuous commutation failure cannot be effectively restrained, and the effect on improving the tr
