DPsim is a real-time power system simulator that operates in the dynamic phasor as well as electromagentic transient domain.

Project description

build status coverage report

DPsim is a solver library for power system simulation.

  • It supports both the electro-magnetic transient (EMT) and dynamic phasor (DP) domains.
  • It provides a Python module which can be embedded in any Python 3 application / scripts.
  • It is implemented in highly-efficient C++ code.
  • It supports real-time execution with time-steps up to 50 uS.
  • It can load models in the Common Information Model (CIM) XML format.
  • It can be interfaced to a variety of protocols and interfaces via VILLASnode.


If you just want to use DPsim for simulations, take a look at the installation instructions.

If you would like to modify / extend DPsim or build it for a specific platform, take a look at the build instructions.


DPsim is a Python extension module which is implemented in optimized native C++ code.

Users can control and script the simulation with Python scripts. Checkout the Quickstart Guide.
