PV System, Grid Interconnected, Wind Energy System, Proportional Integral, AGC and Fuzzy Logic Controller.



The main aim of these paper is to propose a concept regarding the design and modelling of PV-Wind hybrid system and its control strategies. The purpose of these control techniques is to regulate the continuous changes in operational requirements of the hybrid system. In the present scenario, the distribution energy systems play an important role in the distribution systems to maintain the reliability of power systems. The proposed hybrid system is a structure of PV and wind energy system. To achieve the maximum operation from the renewable sources an MPPT methods is proposed. This paper also concentrate to improve the stability of the hybrid system. The stability of the proposed system is improved with the help of a new control strategy implemented for inverter called “Automatic Generation Control”. This control technique is developed with signals from the system parameters i.e voltage and current. A fuzzy logic controller also implemented to get better improvement in stability analysis. The proposed hybrid system is developed and tested in MATLAB/Simulink Environment under different constraints and verified the results.
