Integrating the Solar PV and Wind Energy Systems with the conventional grid has proved to be a great boon to the power industry. In this paper, we shall study about the Solar PV integration, a comparison between the efficiency of Solar PV systems and Wind Energy Systems, the impacts of Solar PV integration with the conventional grid and about the methods to mitigate the problems arising from the increased Solar PV integration (penetration) in the conventional grid. Two or more different system use for making energy called hybrid system. In this paper hybrid system is a combination of wind energy and solar PV array with showing hybrid system is more important than individual one. The proposed DC-DC boost converters are used for both sources i.e. wind and PV having less number of switches. Using PI controller, varying DC output are converted into constant. Hybrid system not only improves the power but also cost of the system. This paper proposed that the power quality improvement of hybrid system using D-STATCOM use in the system. To remove the harmonics in the current and give constant power supply. This proposed hybrid system simulates on MATLAB software. In this paper, Solar PV systems and Wind Energy Systems (hybrid system) serves as the main source for improving Power Quality features. The control strategy for the hybrid system generator is designed from Type-2 Fuzzy Logic Controller (FLC). Most of the applications are worked with high uncertainties. Type-2 FLC have the capability to capture the uncertainties about membership functions of fuzzy sets. For the different voltage instability, hybrid system generator is controlled to cancel out of them. The performance measurement of the hybrid system generator with Type-2 FLC for PQ improvement is validated in MATLAB/Simulink, which show the value of Total Harmonic Distortion (THD) is 0.9103%, power factor is unity and injected values for sag/swell gets better results compared to a traditional technique
