Design, simulation and performance analysis of grid connected photo-voltaic system with decoupled current control
Rapidly increasing demand and climate change leads every country to think about their electricity generation sources. Developing country prefer green energy technology and developed country support them to get good carbon credit. Solar energy is most favorable among all renewable energy source. Grid connected solar plant provide pollution free energy to consumer. As the number of Photo Voltaic (PV) system integrated to grid is increases, it also affects the quality of power. Integrated PV system should follow the standards provided by the utility. One major issue in power quality is harmonic distortion. In this paper 10 kW PV system is simulated and analyzed. Perturb and Observe (P&O) Maximum Power Point Tracking (MPPT) has been used to linearized PV source. Feed forward current control method is used to control the injected power from inverter, which limits Total Harmonic Distortion (%THD) of output current below 5%.
