Power reserve control strategy in the left‐side of maximum power point for primary frequency regulation of grid‐connected photovoltaic systems

IET Power Electronics, 2022
The traditional method of operating photovoltaic (PV) systems on the right side of the maximum power point (MPP) may cause the voltage to be close to the open‐circuit voltage of the PV panel, resulting in a large oscillation of the PV power. In contrast,
