CHT: A Digital Computer Package for Solving Short Term Hydro-Thermal Coordination and Unit Commitment Problems

The main characteristics of a digital computer package for solving the complex problem of Short-Term hydro-thermal unit commitment in medium and large size power systems (over 150 units) are presented. The over-all system design criteria, including Man Machine Interface (MMI), the software tools that support the analysis of the large volume of information required for unit commitment planning, and the optimization algorithms are discussed in the text. The package has been tested on a medium-size power system model.
