Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
The reference values of the active and reactive currents can be expressed as follows: PDC−VDC curves with r = 0 Ω and r = 0.042 Ω, respectively. In the failure mode, the PV inverter operates at point G1 (actual operating point) when r = 0.042 Ω, and the DC voltage rises by 111 V.
