The ODM/OPF schema can be found here
The corresponding ODM-format xml file can be found here.
- map ODM/OPF to InterPSS Object model
An ODM/OPF mapper is developed to map the ODM-format OPF data to InterPSS OpfNetwork object. Now this operation is included in IEEEODMMaper
- running OPF with InterPSS
1) A dc-opf algorithm, based on the open source, Java, Quadratic Programming Solver——QuadProgJ, is implemented with InterPSS APIs. The source codes are here
2) A test case( code ) is run to test the developed algorithm with the data provided above, and the result is verified against what is originally done with QuadProgJ by Jie Li,etc(more reference)
3) Test result:
