PowerWorld Simulator can quickly calculate various linear sensitivities based on the current power flow solution. Calculation is very fast, as it requires only algebraic computations on the Jacobian matrix created when the power flow is solved. 

Available sensitivities include:

  • Power Transfer Distribution Factor (PTDF) – simple and multi-element
  • Shift Factors – simple and weighted multi-element
  • Line Outage Distribution Factors (LODF)
  • Losses
  • Real and reactive flows and voltages
