Announcing Challenge 2

Challenge 2

Challenge 2 is expanding upon the SCOPF problem posed in Challenge 1 by adding adjustable transformer tap ratios, phase shifting transformers, switchable shunts, transmission line switching, price-responsive demand, ramp rate constrained generators and loads, and fast-start unit commitment.

Timeline:  The Challenge 2 competition timeline updated January 29, 2021, is illustrated below and in the Timeline document.
