# PSS test reference: identical to pss_on but WITHOUT a power system stabilizer
# (no `pss` field => no stabilizing signal to the AVR). Used to confirm (a) the no-PSS
# path is unchanged and (b) the PSS measurably affects the post-disturbance dynamics.
# Topology mirrors sp_ground. See docs/algebraic_equations_design.md.
