In this paper, a PV inverter control scheme is presented suitable for operation under distorted and unbalanced grid voltage, as well as when the grid frequency varies, as is the case in isolated systems such as those in non-interconnected islands. The analysis is performed both in the frequency and time domains, using a suitable linearized model, as well as the full non-linear electrical model of the system. The objective is to determine the main factors affecting the system dynamic behavior as well as the power quality characteristics of the PV output current in presence of distorted grid conditions. To this end, a comparative assessment of the proposed PV inverter controller versus a conventional one is performed.
