Abstract: This paper presents a wind-solar hybrid system using solid state transformer (SST) for reactive power compensation to achieve power quality. The proposed hybrid system using SST can effectively suppress the voltage fluctuation. This work proposes a new modelling approach of a combined Photovoltaic and Wind power system. The controller has been designed with fuzzy logic and sliding mode along with SST. This approach enables the design and implementation of efficient controllers for distributed energy resource (DER) hybrid systems. The simulation of proposed work is carried out using MATLAB.
