Abstract：Nowadays, all kinds of distributed generation (DG) systems are developed rapidly. Grid connected inverter as one of the most important parts in the DG system, its controller are always the investigated focus. In order to improve the connected current and the response of the controller, stationary reference frame control strategy with proportional resonant (PR) controller due to its high dynamic and good harmonic compensation performance characteristics is widely used in many different DG applications. This paper proposes a new additional proportional resonant control method with positive sequence grid voltage feed-forward. By using this method, both the quality of grid connected current and the dynamic performance are improved, which also validated by experiments.
