FLoad: how to cap active power during TDS?

[federicagiannunzio]

Hi everyone,

I'm using FLoad for a TDS study where I simulate a dynamic load-altering attack — an attack that manipulates load power in order to cause frequency deviation from its nominal value.

The issue is that during the attack, the injected power P = pv0 · v^ap · f^bp can grow beyond the physical capacity of the load. For example, if the attacked load is rated 5 MW, the power should not exceed that value regardless of voltage and frequency variations. I need a way to dynamically clamp P at runtime so that it caps at the load's maximum rating.

Is there a recommended way to enforce this kind of upper bound on FLoad's power injection in ANDES?

Thanks in advance!
