Abstract
This paper gives a detailed modelling of grid-tied PV system in which we presented a control strategy based on voltage oriented control scheme for grid-tied solar PV inverter which regulates point of common coupling (PCC) voltage and current considering near unity power factor. Hence only active power is controlled which is injected into the grid. For simulation purpose, a three-phase three-level (3L) diode clamped multilevel inverter (DCMLI) is used and a modulation technique having sinusoidal pulse width modulation (SPWM) is also formulated to provide gating pulse to the 3L inverter. The whole system is analysed based on inverter current, grid current and performance of inverter has been carried out. Effectiveness of the control system is studied and results are analyzed based on the total harmonic distortion (THD). The simulation work is carried out in Matlab/Simulink software.
