Development of models for the planning of large scale water- energy systems.

A mathematical optimization model was developed to assist the investigation of various alternatives for future water-energy systems. The capacity expansion problem of water-energy systems considers future water-energy demands (for water, electricity, gas, coal) and the availability of water and coal, and requires the determination of the location, timing, and size of facilities to satisfy demands at minimum cost (including operating and capacity costs). The system consists of four subsystems (water, coal, electricity, and gas), the interactions of which are expressed explicitly in mathematical terms and equations.-from STAR, 21(9), 1983
