“The models we build to conduct these studies are incredibly complex.​ Previously it would take our engineers, using the brute-force engineering judgment method, three to four weeks, up to two months, to get these models to a solved, converged state. Pearl Street can do that for us in about a week or less. The network upgrades we identify to integrate these new amounts of generation [also] become much more realistic.”

“SUGAR™’s performance demonstrated significant time reductions for the queue scenario model-building process: a typical three-week process was reduced to a single working session lasting thirty minutes or less.

• Models produced using SUGAR™ are consistent with current practices in terms of model quality based on comparisons of contingency analysis results (i.e., total thermal and/or voltage violation counts) and simulation convergence.

• SUGAR™ can help automate diagnoses of root causes of non-convergence for mitigation.”
