Notes:
1. The naming of the different test cases depends on their source. In some cases, the number includes the feeder buses while in other cases, it does not.
2. The file format is very similar to the one used in http://www.dejazzer.com/reds.html , but also includes the branch rating. See this readme file for a complete description.
3. The solution files represent the optimal solutions found by the algorithm presented in the paper above for each of the test case. The solution files simply list the open branches that leads to the optimal radial topology of the network in order to minimize the real power losses. The open branch are identified by their index number. The details of the algorithm are provided in the paper cited above.
