Description
Summary:This paper presents a mixed-integer linear formulation for solving a multi-period hydropower production planning problem in a single-reservoir system. The model offers a tractable yet realistic framework for long-term planning of hydropower operations. We utilize a production-driven dispatch model aimed at optimizing water releases at reservoirs and dams to maximize hydropower generation. The approach discretizes water levels, simplifies nonconvex dynamics, and prescribes easy-to-interpret operational curves for release guidance. Key features include a head-dependent hydropower function, upstream flow travel time, smoothing constraints on water release, and a turbine switch-off policy. The model is evaluated using real data from the Lower Mekong Basin. •A tractable and realistic model for long-term hydropower operation planning.•An approach that discretizes water levels, simplifies nonconvex dynamics, and prescribes intuitive operational curves for release guidance.•Incorporates key features, including a head-dependent hydropower function, upstream flow travel time, smoothing constraints for water release, and a turbine switch-off policy.•Validated using real-world data from the Lower Mekong Basin.
