Abstract
Current quality is one of the most important issues for operating three-phase grid-connected inverter in distributed generation systems. In practice, the grid current
quality is degraded in case of non-ideal utility voltage. A new control strategy is proposed for the three-phase gridconnected inverter. Different from the traditional method,
our proposal utilizes the unique abc-frame complex-coefficient filter and controller to achieve the balanced, sinusoidal grid current. The main feature of the proposed
method is simple and easy to implement without any frame transformation. The theoretical analysis and experimental test are presented. The experimental results verify the
effectiveness of the proposed control strategy.
