Due to ever increasing energy demand and depletion of conventional energy resources, there is a need to generate and fulfill this gap, using clean and green energy resources such as Solar Photo-Voltaic (SPV), Wind Energy System (WES), Fuel Cell and Biomass etc. PV and Wind are abundantly and easily available in the nature. Combining these two intermittent sources are always challenging in the term of sustainability and power quality, so an intelligent technique is required for supplying the reliable, sustainable, and maximum quality power to the power grid and domestic load. In this paper, the power generated by SPV and Wind Turbine (WT) with Maximum Power Point Tracking (MPPT) has been collected on the common coupling point. Then single stage converter along with Proportional-Resonant (PR) based current controller has been used to transfer reliable and maximum power to the grid, in MATLAB/SIMULINK environment. In this system, due to high cost, battery utilization has been minimized and intelligent algorithm has been adopted to transfer maximum available solar and wind power into the grid. Further, using the PR controller, the converter reference tracking performance has been enhanced and shortcoming associated with conventional PI control has been alleviated for reliable and stable grid connection as per the IEEE standards. The simulation results of 1 kW show the control performance and dynamic behavior of the grid interfaced PV-wind system.
