Advanced power flow solutions and contingency power system analysis

The steady state analysis package for PSLF allows users to perform traditional thermal and voltage analysis, static voltage stability analysis, and transfer limit analysis. Thousands of contingencies can be simulated in each run. Steady state analysis tools (SSTOOLS) offers users tremendous flexibility in specifying contingencies and simulation options.

  • Create N–1, N–1–1, and N–2 contingencies within our automated contingency creator, SSTOOLS.
  • Easily generate control and case files.
  • Execute transmission planning, interconnection analysis, and contingency analysis.
  • Build custom contingencies for specialized use cases.

A faster, easier approach to dynamic analysis

The dynamic analysis package in PSLF software allows users to perform transient stability analysis for multiple events on cases containing up to 125,000 buses. Run this tool in batch mode and execute multiple dynamic simulations without user interaction. Model and simulate remedial action schemes (RAS) within dynamic simulations.

  • Perform transient stability analysis for multiple case events.
  • Evaluate new or modified remedial action schemes within dynamic simulations.
  • Access models for wind turbine-generators, solar photovoltaic production, and energy storage.
  • Create and use your own equipment models with EPCL.
