1. A power system comprising:
an inverter comprising an LCL filter, the LCL filter comprising a first inductor, a capacitor, and a second inductor; and
a controller configured to:
determine an electrical characteristic of an output of the inverter, wherein the electrical characteristic of the output of the inverter comprises a measured Total Harmonic Distortion (THD) of an output current of the inverter; and
based at least in part on the determined electrical characteristic of the output of the inverter, dynamically adjust damping of the LCL filter, wherein the damping of the LCL filter is dynamically adjusted in response to a determination that the measured THD exceeds a threshold.
