Abstract A method for optimal scheduling of electric energy production of hydro-thermal power systems is presented based on benefit-efficiency analysis in this paper. The mechanism of converting hydro-energy into electric energy in the hydroelectric stations is also studied, taking potential energy, kinetic energy, water-deep pressure energy and reservoir energy into consideration. The reservoirs energy proposed in this paper is influenced by such factors as reservoir capacity and bottom shape. A model of electric energy production of hydro-thermal power systems for benefit maximization is proposed, in which the power efficiency measured in unit time is included, and the optimization problem is solved with sequential quadratic programming. A sutied example is used for illustrate the feasiblity and applicability of the proposed model.
