# Challenges

TESTING ENVIRONMENT (closed)

The sandbox is a testing environment that allows Entrants to try the submission, evaluation, and scoring process using small datasets. ARPA-E approval of Team required.

FINISHED

Challenge 1 solved a security-constrained (AC) optimal power flow (SCOPF) problem. Algorithms were tested on complex, realistic power system models, and Entrants were scored on how well their algorithms perform relative to other Entrants’ algorithms.

FUTURE

Future competitions, beginning with Challenge 2, are expected to build on the models used in Challenge 1 and may include complicating factors such as solving larger network models, optimizing power flows over both transmission and distribution systems, and stochastic optimization.
