Abstract:

The proportional resonant (PR) controller is a real alternative to the standard proportional integral (PI) controller referring to its effectiveness and superior performance when controlling sinusoidal waveforms and its capacity to compensate for low order harmonics using the harmonic compensator (HC). The resonant frequency value is required for both PR and HC's internal models. The nominal value of the grid frequency and its multiples are employed in most cases, however, when the grid frequency fluctuates, the performance of both PR and HC suffers. This work proposes an adaptive proportional resonant (PR) controller for a three-phase grid-connected inverter this controller can adapt its control parameters during the grid frequency fluctuations based on the information issued by the SOGI-FLL, this concept helps to enhance the behavior of resonant controller and harmonic compensator in the case of grid frequency deviations. Further, the effectiveness and robustness of the suggested adaptive resonant controller for grid-tied inverters are clearly demonstrated by simulation results using the matlab environment.
