iPST: the open-source project for power grid simulations

The iPST project aims at developing of an open-source platform dedicated to large power grid security analysis. It is dedicated to :

  • Power system simulations, be they static through Power Flows and Optimal Power Flows or dynamic through dynamic power system simulators.
  • Power system data-mining thanks to big-data databases that allow storing time-series of power system related data.
The core of the project is composed of the iIDM (iTesla Internal Data Model) which allows to import, export and edit power system models. The computation modules are plugged onto this core. The core also includes computation distribution functionalities based on MPI (Message Passing Interface).

Join the iPST session in Paris on Thursday 1st June 2017

The development roadmap for 2016-2017 is described in this presentation:


The document details the following aspects:

  • Partners and organization
  • Current state of the project: What is open-source, what is not.
  • Future functional perimeter: New features in 2016-2017.
  • Usability improvements: Decrease the learning curve.
  • Communication


Depending on you need, different documentation is available:

  • The github project, including its wiki.
  • The javadoc for developers.
  • The validation handbook for final users.
  • The iTesla FP7 project web site, as an archive of the work achieved between 2012 and 2016.
