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.

AC voltage detected on PV input terminals

When the inverter is on, even if PV is disconnected, there is a voltage detected at the PV IN terminals (equal voltage of about 130v AC on all PV input terminals (both - and + PV input). The voltage causes a test screw driver to light up (showing there is significant AC voltage present) and by a multimeter I measured 130V AC between the PV IN terminals and ground.
