From: A new frequency approach for light flicker evaluation in electric power systems
Percentage errors in estimation of P st versus lower frequency of symmetric interharmonic pairs producing AM and unitary P st . \( {\mathrm{P}}_{\mathrm{st}1}^{\mathrm{BASE}},{\mathrm{P}}_{\mathrm{st}1}^{\mathrm{I}},{\mathrm{P}}_{\mathrm{st}1}^{\mathrm{I}\mathrm{I}} \) and \( {\mathrm{P}}_{\mathrm{st}1}^{\mathrm{III}} \) indicate the short-term flicker severity index considering, respectively, the analytical estimation proposed in [7] (cyan), the AC and the DC component of PU1 (17) (blue), only the DC component of PU1 (18) (green) and only the PU1_DC1 component of PU1 (19) (red).
