Energy storage converter virtual synchronization adaptive control method based on fuzzy theory

The invention discloses an energy storage converter virtual synchronization adaptive control method based on a fuzzy theory, and designs a VSG control system for an energy storage system converter based on a fuzzy control theory.The VSG control system is used for simulating characteristics of a synchronous machine excitation regulator, a prime motor speed regulator and a synchronous machine rotor motion equation. The system is mainly composed of a reactive power-voltage control module, an active power-frequency control module and a virtual parameter adaptive optimization module. The reactive-voltage link of the VSG mainly simulates the reactive-voltage droop characteristic of a synchronous machine; the active-frequency link of the VSG mainly simulates the active-frequency droop characteristic of a prime mover speed regulator and a second-order model of a rotor motion equation of the synchronous machine; and in the virtual parameter adaptive optimization link, fuzzy control is adopted to determine the value of
