PowerFlows.jl

Overview

PowerFlows.jl is part of the National Laboratory of the Rockies' Sienna platform, an open source framework for scheduling problems and dynamic simulations for power systems. The Sienna platform can be found on GitHub.

PowerFlows.jl provides a uniform interface to multiple power-flow formulations and solvers for PowerSystems.jl data models. Main capabilities include:

  • DC power flow — bus-angle formulation and PTDF-based (dense and virtual) methods, with optional multi-period solves.
  • AC power flow — polar, rectangular current-injection, and mixed current–power balance formulations.
  • Iterative AC solvers — Newton–Raphson, trust region, Levenberg–Marquardt, and robust homotopy options.
  • Multi-period DC workflows — batch validation of time-coupled dispatches (for example, post–unit commitment checks).
  • Post-processing and export — structured DataFrame results, optional PSS/E export, loss and voltage-stability factors.

The package builds on network matrices from PowerNetworkMatrices.jl and is commonly used with operations simulations in PowerSimulations.jl (both power-flow-in-the-loop and post-solve validation). Test systems for the tutorials come from PowerSystemCaseBuilder.jl.

PowerFlows.jl is under active development; we welcome feedback, suggestions, and bug reports.
