Active/reactive power control of photovoltaic grid‐tied inverters

During Normal operation, the dc–dc converters of the multi-string GCPVPP (Fig. 1) extract the maximum power from PV strings. However, during Sag I or Sag II, the extracted power from the PV strings should be reduced due to the current limitation of the inverter. Therefore, a modification in the controller of the dc–dc converters is necessary.
