Reactive power control strategy for integrated photovoltaic inverter

Rising penetration of photovoltaic (PV) power also poses several threats to electrical system which demands proper inverter control schemes be designed. One major issue is that as PV systems are inherently non-inertial in nature, they do not participate regulating voltage or reactive and hence become highly sensitive external disturbances. Any perturbation frequency may cause some serious consequences terms loss transient stability reliability. Thus controlling the for smooth operation while interfacing with grid brings a challenging task maintaining both well within acceptable limits. Another important aspect intermittency output application advance tracking algorithms. Therefore, novel strategies have been presented this paper. The proposed synchroconverter based controller enables inject active powers facilitates integrated withstand perturbation. Whereas an enhanced algorithm applied here can estimate panel parameters precisely offering effective any conditional variance. Proposed controllers analyzed through simulations different spans time according variations.
