Abstract

This chapter reviews the state-of-the-art modeling and solution methodologies for a deterministic security-constrained unit commitment (SCUC) and extends the results to the solution of SCUC with uncertainties, for effectively managing uncertainties and enhancing the economics and security of power system operations. It includes numerical case studies, which indicate the effectiveness solution methodologies with substantial practical and computational requirements. The chapter reviews existing models and solution methodologies to effectively handle uncertainties in the SCUC problem for enhancing the power system economics and security, with a focus on the short-term operation. The SCUC solution provides an hourly generation schedule for supplying the power system demand and meeting the security margin, and an hourly generating reserve schedule for satisfying operating constraints when unexpected changes occur in the power system demand. The hourly generating reserve schedule satisfies operating constraints in case of contingencies or unexpected changes in demand.
