One of the major issues while interfacing is that as PV systems are inherently non-inertial in nature, they do not participate in regulating the voltage or reactive power and hence become highly sensitive to external disturbances. Any perturbation in voltage or frequency due to factors like sudden load changes, loss of a generation unit or line switching may cause some serious consequences in terms of loss of transient stability and reliability. Thus controlling the PV inverter for smooth operation of system while interfacing with the grid, brings a challenging task of maintaining both voltage and frequency well within the acceptable limits. Further, another important aspect for PV interfacing is its intermittent output characteristic which varies dramatically with the operating conditions and hence demands designing of some advance tracking algorithms which should be effective for any rapid changes in the environmental parameters. Therefore, from a reliable and enhanced functional perspective novel control strategies for PV interfacing have been presented in this paper. The proposed synchroconverter based inverter control strategy enables the injection of active and reactive power and thus facilitates the integrated PV system to withstand voltage or frequency perturbation. Whereas an enhanced model-based (MB) algorithm is applied here that estimates the panel parameters precisely and offers efficient and effective tracking for any conditional variance. Key words: Interfacing, inverter, non-inertial, perturbation, reactive power, synchro converter. Cite this Article: Md.
