“…The latter allows indirect control of currents drawn from the grid by converting these inverter currents into active and reactive powers using three-phase systems. The results obtained with the new control methods SPWM and SVPWM show their performance superior to the simple modulation applied to different levels of inverters in the previous article [28], [29]. After analyzing the simulation results of the control method, it was found that the harmonic distortion of the current under load is much lower than the international standard (<<5%) for the two control methods, with a better THD of (SVPWM) compared to that obtained by sine wave control (SPWM).…”

Currently, the energy transfer process to the grid of the PV system is based on the importance of less harmonics and high efficiency. The evaluation of harmonics distortion of current is based on the value of THDi (<<5%), this last becomes very high if the current leakage is high, which causes losses of the grid and safety problems. Therefore, our job is to improve the classic control method of PV inverters used to reduce grid loss and improve electricity prices. This study is a proposal toward the modelization and improvement of the three-phase two-level, and multi-level photovoltaic (PV) inverter command, using space vector, and sinusoidal control based on controlling the active and reactive current delivered into the grid indirectly with a resonant controller (PIR) for a nonlinear load (NLL). The results of the simulations obtained by the new control methodology, SPWM, and SVPWM show that its performance is better compared with the simple modulation (PWM); the total harmonic distortion (THD) of current in both methods (SVPWM) and (SPWM) is better than that obtained with conventional commands. Also, multilevel converters control produces better quality waveforms, reducing current harmonic distortion.
