Design a new compensation control strategy for gridconnected WT and MT inverters at the microgrid

Abstract

The use of the a new control method for grid-connected inverters for reducing the output current harmonic distortion in a wide range of grid-connected distributed generation applications, including wind turbine (WT) and microturbine (MT) inverters is proposed in this paper. The propose control method designed to eliminate main harmonics in microgrid (MG) and between MG and point of common coupling (PCC) and responsible for the correction of the system unbalance. Another advantage of the proposed control method is that it can be easily adopted into the distributed generation (DG) control system without the installation of extra hardware. The proposed control method is comprised of the synchronous reference frame method (SRF). Results from the proposed control method are provided to show the feasibility of the proposed approach.
