Self-adaptive optimization regulation and control method under fault of true bipolar flexible direct-current power transmission system

The invention discloses a self-adaptive optimization regulation and control method under a fault of a true bipolar flexible direct-current power transmission system. The method comprises the followingsteps of acquiring a tidal current state, a topological state, power grid parameters and new energy field information of a direct-current power grid in real time; determining a new energy maximum absorption target function expression; analyzing the constraint conditions of the true bipolar direct-current power transmission system; generating an anticipated accident set; and establishing an equivalent optimization model of the whole system, solving a corresponding optimization regulation and control scheme for all anticipated accidents in the anticipated accident set, and forming an offline optimization scheme library; when the system actually fails, immediately matching and applying the most similar optimization scheme in the offline library, and calculating and applying an accurate real-time optimization scheme
