Decrease in Psti and Plti values with transposed Pst and Plt (@LV) to HV?

Do Psti and Plti values decrease when the measured Pst and Plt (@LV) is transposed to HV?

Could you provide a context to this question?

Welcome to PF.
I guess the subject is; The quality of AC power. Flicker emission limits for energy users on a power distribution network.
Pst; short term parameter.
Plt; long term parameter.
Power-line flicker is a visible change in brightness of a lamp due to rapid fluctuations in the voltage of the power supply. The voltage drop is generated over the source impedance of the grid by the changing load current of an equipment or facility. These fluctuations in time generate flicker.

Flicker is a multi-cycle effect. I see nowhere to store several cycles of energy in the step-up transformer. I therefore assume that flicker will not be significantly attenuated by the LV to HV transformation at the generation site.

To reduce flicker from static inverters would require something equivalent to a synchronous motor/generator, with a heavy flywheel.
