   - disturbance type: string, either "Short circuit" or "Load Step up"
   - disturbance duration: float, duration of the short circuit in seconds, otherwise 0
   - sc type: integer, 0 for load step up, 1-10 for short circuit type identifier

   - R1, R2, R3: float, per-phase resistance values of the stochastically sampled random load (Ω), used for load disturbance.
   - L1, L2, L3: float, per-phase inductance values of the random load (H), used for load disturbance.
   - C1, C2, C3: float, per-phase capacitance values of the random load (F), used for load disturbance.
