Getting started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

In order to build powsybl-open-rao, you need the following environment available:

  • Install JDK (21 or greater),
  • Install Maven latest version.

Installing

OpenRAO needs a load flow implementation and a sensitivity analysis implementation at runtime, following the interfaces of powsybl-core which documentation is available here. Note that for obvious reasons, included performances, reliability and transparency, OpenRAO uses Powsybl Open Load Flow by default, but you can prefer you own implementation.
