Summary:A method and a device for controlling grid configuration of a flexible direct current electric power transmission system, and a computer-readable storage medium are provided. The active power reference value is modified based on the frequency deviation of the alternating current grid. The reactive power reference value is modified based on the voltage deviation of the alternating current grid. The outputted active power and the outputted reactive power are controlled based on the active power reference value and the reactive power reference value, respectively. The grid voltage is further configured and controlled through power control, so that the system is capable of self-synchronization, frequency regulation and voltage regulation. In addition, the virtual synchronous machine technology is introduced into control of the reactive power, so that the system can provide inertia support for the grid voltage amplitude.
