Abstract: The hydropower unit commitment problem is a complex decision-making process involving the integrated hourly scheduling of generators in a multi-project hydropower system. The purpose is to satisfy power load demands, water demands, reliability constraints, operational restrictions and security requirements. A dynamic programming (DP) optimization model is developed which maximizes basin-wide operating efficiency subject to: (1) plant constraints on total generation requirements, generation shape requirements, and spinning reserve; and (2) operational restrictions on rough zone avoidance, minimum up and down time requirements and unit outage modes. Application of the DP model to the hydropower system of the Lower Colorado River Basin demonstrates the capabilities of real-time optimal unit scheduling in satisfying complex operational constraints while improving basin-wide generation efficiency.
