Electrical and electronic devices are prone to failure when exposed to one or more power quality issues. The purpose of this research is to improve the power quality in a three-phase four-wire distribution grid by using a fuel cell integrated unified power quality conditioner (FCI-UPQC). On the shunt side, the proposed FCI-UPQC has a four-leg converter and a three-leg converter on the series side. The FCI-UPQC reference signals are generated using a combination of synchronous reference frame and instantaneous reactive power theories. In addition, an adaptive neuro-fuzzy inference system (ANFIS) controller is proposed in this study to maintain the DC-link voltage in the FCI-UPQC. The ANFIS controller is built in the style of a Sugeno fuzzy architecture and is trained offline with data from the proportional-integral controller. The obtained results demonstrated that the proposed FCI-UPQC compensated power quality problems such as voltage sag, swell, harmonics, neutral current, source current imbalance in the three-phase four-wire distribution grid. The presence of fuel cell in this work makes more effectiveness of the proposed system by providing real power support during supply interruption on the grid side.
