Simulation Study&Modeling of Grid Connected Single Phase PV System

In this paper we are study of simulation of grid connected PV MATLAB software. In this work we present a new method for the modeling and simulation study of a photovoltaic grid connected system and its experimental validation. When the PV system is connected to the grid, it can transfer the extra energy to the grid after fulfilling the local demand. But when the system generates less than what is required to support the local demand, than extra energy is extracted from the grid. Thus PV solar energy acts as an alternative resource of electricity. The PV system, The validation of model is through Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE). Results showed that inverter output power from simulation is acceptable with small deviation from the actual data. This is due to inaccuracies of predicting de-rating factors listed in this work. The simulation results have been performed through Matlab/Simulink environment. Results has shown good agreement with experimental. The significant error indicators are reported in order to show the effectiveness of the simulation model to predict energy generation for such PV system.
