iPST: the open-source project for power grid simulations

The iPST project aims at developing of an open-source toolkit 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). The 2017-2018 development roadmap is available here.
