Methods of scheduling a hydro-thermal power system for optimum economy Smith, Bryan Robert


In this thesis an attempt has been made to improve upon and to compare existing methods of scheduling a hydro-thermal power system. Two methods in particular, the coordination-equations method and the incremental dynamic programming method, were investigated in detail. Numerical calculations based on these two methods were carried out for a two-plant system on an Alwac III-E digital computer, a medium-speed computer with a limited amount of random-access memory. The economical solution of these equations for a larger system would require a faster computer with a large random-access memory and preferably automatic floating point arithmetic. The results obtained indicate that economic scheduling becomes important only for large power systems. It also appears that the dynamic programming method is the more suitable for digital computer solution.
