In order to improve the output stability of the transmission and distribution switch,the automatic control method of the transmission and distribution switch based on flexible DC was proposed.The parameter automatic identification model of the automatic control of the transmission and distribution switch of the flexible DC was adopted,the fuzzy control of the transmission and distribution switch of the flexible DC was carried out by the fusion characteristic analysis method,the output parameter identification of the transmission and distribution switch was carried out by the fusion parameter estimation method,the robust characteristic analysis model of the transmission and distribution switch was established,the system oscillation regulation and stability control of the transmission and distribution switch was carried out by the positive damping parameter regulation method,the virtual resistance stability control method was adopted,the oscillation peak suppression method was used,and the damping regulation of the automatic control of the transmission and distribution switch was carried out by the flexible DC analysis method to realize the automatic optimization control of the transmission and distribution switch.The simulation results show that the automatic control of transmission and distribution switch with this method was more stable and the output robust,which improves the automatic control level of transmission and distribution switch.
