- Abstract
Based on Floquet theory, a simple and fast time‐domain stability analysis method for an N‐parallel inverters system is proposed. Furthermore, a general time‐domain model of the N‐parallel inverters system in grid‐connected mode and in island mode are derived, and the corresponding stability criteria are derived based on the Floquet theory. Subsequently, simulations and experiments of a two‐parallel inverters system in island and grid‐connected modes are conducted to verify the correctness and effectiveness of the proposed time‐domain stability analysis method. To the end, the complexity comparison between the proposed time‐domain method and the traditional frequency‐domain method is presented to prove the advantages of the proposed method over the tedious manual derivation.
