• Disturbance and control action
• ODM data format
  • Currently, there are three ways to generate the corresponding xml files:
1. Use the on-line transfer service, located here;
2. Check out the project source codes and run it by Eclipse for example. The source codes are located at here.
3. Create it manually following the steps here.

The corresponding xml file for transient stability simulation can be found here.
