Economic System Operation Considering Valve Throttling Losses II-Distribution of System Loads by the Method of Dynamic Programming

Minimum fuel cost dispatches have been determined for a group of steam turbine-generators by an algorithm employing dynamic programming. The algorithm permits accurate recognition of the "loop effect" in the input-output function caused by the throttling losses in steam admission or governor valves. A digital computer program has been utilized to compare the fuel costs resulting from several common dispatching criteria. A close approximation to the optimum dispatch was obtained with the stepped incremental method.
