Abstract: This paper introduces an advanced current control strategy for distributed generation into the utility grid despite the distorted grid voltage and RC loads. The proposed current controller is designed in synchronous reference frame and composed of a fuzzy logic controller. The fuzzy logic controller greatly simplifies the control strategy. It does not require the local load current measurement and harmonic analysis of the grid voltage. Therefore, the proposed control method can be easily adopted into the traditional DG control system without installation of external hardware. The operation principle of the proposed control method is analyzed in detail, and its effectiveness is validated through simulated results.
