Multi-direct-current commutation failure recovery priority determination method, system, equipment and medium

The invention provides a multi-direct-current commutation failure recovery priority determination method, system and device and a medium, and the method comprises the steps: obtaining the direct-current commutation failure recovery capability according to the obtained direct-current equivalent impedance and Thevenin equivalent impedance of each direct-current access point; performing voltage reactive power sensitivity analysis on each direct current access point to obtain a comprehensive influence index of direct current recovery on the direct current in the network, and correcting the comprehensive influence index of the direct current recovery on the direct current in the network according to the obtained total capacity of the dynamic reactive power support equipment of each direct current access point to obtain a comprehensive influence index of the direct current recovery; and obtaining a direct current recovery priority according to the obtained maximum commutation failure bearing frequency of each direc
