The submission window was August 31-September 4, 2023. 

Scoring

Division 1, 2, and 3 rankings will be determined based upon the total score (Market Surplus, zms in the Formulation Document). Only zms values that are positive for feasible solutions will be counted. All other results will be treated as 0.0. 

Division 4, 5, and 6 rankings are based on the count of top scores for each scenario in Divisions 1, 2, and 3.

See the Scoring document for details. All Divisions in Event 4 will receive prizes. The Benchmark score is included for reference. The Benchmark had only a single best score but it was excluded from the counts.

LEADERBOARD RANKINGS

Ensemble is the set of best scores for the grouping. The Sum of all scores data is provided for comparison. There are  prizes in 6 categories; 3 for sum of scores and 3 for number of best scores. There are 283 scenarios in Division 1, and 192 in both Divisions 2 and 3 for a total of 667 scenarios. A total of 669 scenarios was run for each team but no one produced a positive Market Surplus for Divisions 2 and 3 for scenario 4 of the 23,643-bus network so it is ignored.

The scores were posted September 21, 2023.

ARPA-E has reviewed and approved the prizes.

The following table is presented for comparison only; it has no impact on awarding prizes although the column listing the number of best scores is the same as the results in the count of all divisions above. The single Benchmark best score for C3E4N06708D3 scenario 126 switching allowed has been removed, but the results for second best, third, etc. are as they occurred. One scenario only had 4 positive scores. That 71% of the teams had at least one best score and 86% had at least one second best score speaks to the quality and diversity of the submissions.
