APFC Panel is used to maintain the power factor near unity
by adding capacitance across the load.
P = V x I x Power factor.
100 = 100 x 1 x 1 ( Idle case)
If power factor decrease to 0.1
100 = 100 x 10 x 0.1

Here we can observe that current in circuit increased
from 1 amp to 10 amp with decrease in power factor from 1
to 0.1

This is the effect of low power factor in system. Due to
this increased current higher rating of cables , breakers
etc required. also due to this increased current we require
more power generated as MVA demand shoots up.

why ss stablity limit is more transient stablity limit?
