This study establishes a Dynamic model of grid-connected PV system by MATLAB/Simulink with d-and q-axis as coordinates which is synchronously rotating with the grid voltage to reflect the characteristics of the system accurately. Solar energy has emerged as one of the most promising new energy sources; it doesn't require large, lossy batteries when used in conjunction with grid-connected photovoltaic (PV) systems. Reduced transmission and distribution losses and less environmental contamination are achieved by distributed generation and on-site PV system supply. Based on the accurate modelling system, optimum control and fault analysis are studied. The simulation and analysis verify the effectiveness of the proposed algorithm, and demonstrate that the proposed control system has good static performance. Simulation and analysis results show that the model can correctly reflect the system characteristics and the methods can meet the actual needs.
