AC and DC voltage control method for off-grid inverter based on matching control

Abstract

Abstract Matching control is a new kind of grid-forming control method, compared with droop control and VSM control, it is more stable in a hybrid grid where the synchronous machines and inverters coexist. We introduce the matching control’s concept and developing process briefly, and use the matching control as the inner loop. We propose the VF outer loops to control DC and AC voltage to realize voltage and frequency control in disturbances. Finally, we use Simulink to validate the effectiveness of designed outer loops.
