Since the capacitor and transformer impedances are based on the relevant power frequency, that frequency is the fundamental for the harmonic order calculation. On other words, the formula is valid for either 50 or 60 Hz as long as the capacitor bank VAR rating and the short circuit VA are stated or calculated based on the frequency of interest.
The capacitor self-resonant frequency causes your capacitor to stop behaving like a real capacitor and start behaving more like an inductor at high frequency. This important effect is unnoticeable at low frequencies, but it becomes a major problem related to signal integrity, power integrity, and impedance matching at high frequencies.

The DC-Link capacitor must regulate voltage and absorb ripples in the current, as well. A ripple wiggles the level of the voltage that appears across the DC-Link capacitor while the switching current''s ripple travels through the capacitor (V=IR). One must also consider inverter switching frequencies that the DC-Link capacitor must tolerate.
