| description | The invention discloses a grid-connected converter instantaneous power control method, which belongs to the technical field of power electronic conversion, and comprises the following steps: extracting positive sequence components and negative sequence components of grid voltage and grid-connected current under a two-phase static orthogonal coordinate system; obtaining instantaneous positive-sequence and negative-sequence active and reactive components of the grid-connected converter; decomposing the active instruction and the reactive instruction into a positive-sequence active instruction, a negative-sequence active instruction, a positive-sequence reactive instruction and a negative-sequence reactive instruction according to three different control targets; positive sequence active power, negative sequence active power, positive sequence reactive power and negative sequence reactive power are respectively adjusted by using a closed-loop control loop; and generating a driving control signal of the grid-conn |
