Conclusion This paper proposes a fuzzy-based control strategy for the grid-connected solar photovoltaic system to participate in primary frequency regulation without any energy storage support. A combined fuzzy based de-load control and control mode selector was proposed to enable PV operation at a scheduled level of power reserve.

The main contributions of the paper are: The available power system inertia is considered in adaptive frequency support from DPV inverters. In this case, under low penetration of DPV inverter (high inertia system), the DPV inverters inject their maximum power to the grid.
Accordingly, the DPV system extracts the maximum available power from the PV strings, regardless of the grid frequency conditions. Consequently, the PV system does not support the grid during under-frequency disturbances, as no power reserve is available in the DPV system.
A new frequency control strategy based on the PV system being forced to participate in the inertial response by moving its operating point away from the maximum power point only when the inertia of the system is unsatisfactory to process the initial frequency excursion .
Proposing an adaptive approach for frequency support with distributed photovoltaic systems. Obtaining faster frequency response with injection of higher amount of power to grid during under-frequency. Demonstration of improved frequency response using the composite load model of a distribution feeder.
