A theoretical analysis of the classic hydro-thermal optimization algorithm in power system scheduling

Analyzes the classic hydrothermal optimization algorithm in power system scheduling. The algorithm is derived from a Lagrangian duality formulation of the scheduling problem. Its convergence properties are studied, and under simplifying assumptions conditions for convergence are established. Convergence can be guaranteed for the relaxed classical algorithm. The convergence conditions as well as the relaxation coefficient depend solely on the sensitivities of the hydro and thermal scheduling functions.<
