Analysis of D-Q Small-Signal Impedance of Grid-Tied Inverters

Bo Wen, Dushan Boroyevich, Rolando Burgos, Paolo Mattavelli et al.

Short summary

Grid-tied inverters exhibit a negative incremental resistance in their q-q impedance channel, a consequence of grid synchronization, with PLL bandwidth and inverter power rating dictating its frequency range and magnitude.
