Resource transition model under MISO MIP based Look Ahead Commitment

MISO is in the process of implementing Look Ahead Commitment (LAC) to bridge the gap between Reliability Assessment Commitment (RAC) and Real Time Security Constrained Economic Dispatch (RT-SCED) timeframes. This paper introduces two models in LAC pre-processing logic. The first one is anticipatory startup and shutdown model to account for resource megawatt output during resource startup and shutdown. The second one is an infeasibility identification model to identify data conflicts between state estimation, unit commitment plan and offered parameters. The goal of these two modules is to properly estimate non-dispatchable resource outputs and resolve infeasibility from input data so that LAC can achieve good Mixed Integer Programming (MIP) solutions.
