This work is devoted to solve reactive power and poor power factor problems that occur during the integration of renewable energy sources into the grid. For that, a Distributed Static Synchronous Compensator (D-STATCOM) is proposed. A comparative study of the compensator performance is done with a linear PI-feedforward control technique and a decoupled adaptive fuzzy logic control (AFLC) method. The last one outperforms and it reduces the number of control loop, eliminates the interaction of LCL filter parameters. The AFLC damps the resonance phenomena and reduces the effect of harmonics on the power system around the resonance frequency. In addition, the AFLC had carried robustness even in the presence of structured and unstructured uncertainties. The investigation shows that the performance of the compensator is improved at the presence of the AFLC where the measured values track references perfectly without any overshoot.
