Capacity Expansion model for large‐scale water‐energy systems

A mathematical optimization model has been developed to help investigate various alternatives for the capacity expansion of water‐energy systems. The system consists of four subsystems: water, coal, electricity, and gas systems. Expressing new capacities, production, and distribution activities mathematically, the mathematical structure of the problem is defined and formulated as a multisystem, multiperiod capacity expansion problem. Benders decomposition is applied to the original problem to decompose it into three problems: capacity, production, and distribution problems. Each problem is solved by specialized algorithms. An example problem was solved, and the results are presented.
