Abstract
En 中文
• We consider the unit commitment constraint screening problem under forecasting uncertainty, which holds great potential for accelerating UC solution and providing reliable decisions. • This work takes an early step in extending the classic deterministic screening framework to accommodate uncertainty-aware UC models. Both principled modeling and solving techniques are proposed for constraint screening under uncertainties. • This work improves the screening efficiency by developing novel affine policies to replace the screening model and proposing a multi-area screening approach for large-scale systems.
