This Task Force explores the potential for open source software (OSS) in the power system engineering community. The mission of the Task Force is to diffuse the philosophy of OSS in the power systems community.

The whole idea of OSS is to encourage others to join and contribute. We believe that the most important thing for this Task Force is to get people interested and involved.

To get this result, we collect in this web page an as complete as possible list of open source software packages for power system analysis. Open source means that the full source code is provided. When specified, the software are also free, i.e. can be obtained free of charge and can be freely modified and redistributed.

To better diffuse OSS philosophy, we are also preparing a report that describes the state of the art of OSS for power systems analysis and resumes the contributions of two panel sessions on OSS held at the last IEEE PES General Meetings (Montreal 2006 and Tampa 2007).

Any contributions, ideas or suggestions are very welcome. If you are interested in becoming a member of the OSS Task Force, want to contribute your software, or simply give your suggestions, please contact Prof. F. Milano.
