Abstract
Abstract
This paper establishes the impedance model of a grid-following converter without grabbing control delay and frequency coupling effects into attention, and uses the sinusoidal linearization to operate method to create both sides of the sequence impedance model in order to study the oscillation problem of power systems that contain renewable energy. The grid-connected system’s stability will be evaluated in light of this. MATLAB/Simulink simulations were completed to inspect the veracity of the created resistance model and the reliability analysis results.
