Download (56.5 MB) the Version 7 Sandbox (C2S7N*) datasets; 16 models, 80 scenarios posted March 5, 2021. These synthetic datasets represent the kinds of problems that will be used in Trial 2, with the exception of the industry datasets. A spreadsheet listing the characteristics of each of the 80 scenarios is also available. The differences between Divisions 1 & 3 and between Division 2 & 4 will represent the impact of line switching. None of the Version 7 datasets are exactly the same as the corresponding Version 6 datasets. Be sure to download the latest Evaluation code, described at the bottom of the Evaluation page, to score your own results.
Note on scenarios with negative values of zinf: Scenarios with a negative zinf(defined in section D.2 of the Problem Formulation) are possible and generally reflect high penalties imposed on the solution by a poor prior operating point. The GO Competition does not intend to use such scenarios in any Trial or Final Events. There were, however, 3 such scenarios in C2S7N*, specifically, C2S7N12209 scenario 4 (-16,673,022) and scenario 8 (-99,958) and C2S7N14212 scenario 3 (-13,205,325,795). The first two are the result of legitimate, but poor, prior operating points. The later, however, was the result of an error in constructing the data that resulted in a bad power balance. This scenario has been replaced with one with a zinf value of 7,610,313. The only difference between the new scenario and the old is better values in the raw file for the VM and VA parameters in the Bus Data block and PG and QG parameters in the Generator Data block. The new scenario replaces C2S7N14212 scenario 3 when making Sandbox submissions after March 12, 2021.
Please specify C2S7Nxxxxx (or C2S6Nxxxxx for Version 6) as the model along with dataset=C2_Sandbox and the scenario number in submission.conf when making Sandbox submissions.
Download (665 kB) the Sandbox network model (C2S6N00617) with 10 scenarios. Added February 1, 2021. This new sandbox dataset has gone through more rigorous testing and validation to ensure that the new features included in Challenge 2 will have an impact on the best solutions.
Download (13.1 MB) the Sandbox set of 12 network models and 38 scenarios. Caution: The zip file from 11/20 padded the end C2S6N11152/scenario_001/case.json with many null bytes for unknown reasons. Do not use it.
This version (C2S6N*, posted Nov. 22, 2020) fixes some cost function and transformer tap issues and an error introduced in C2S5N*. It includes a csv file with details about each of the 38 scenarios (refererences to C2S5 should be C2S6). Fixing the transformer taps changed the number of buses in some network models so the naming is slightly different from the C2S4N* version as are the zinf values given in the csv file.
Use the submission.conf file described in Languages to specify necessary runtime parameters including software modues, dataset, network model, and scenario number. Copy and paste into the submission text box.
