Abstract: Emission of carbon and other flue gases into atmosphere is the main drawback of conventional power plants with fossil fuels as source. Renewable energy sources are trending in power generation sector due to global constraints. This paper presents the analysis of grid integration of renewable energy source. The power generated from renewable source is fed to grid. Square wave (conventional two-level) inverter acts as an interface between distributed generation (DG) (from renewable source) and grid. Power switches of square wave inverter are triggered by the pulses generated from synchronous reference theory. The system is validated with fixed current reference condition and variable current reference condition. Proposed system is developed and the result analysis is presented using MATLAB/SIMULINK software
