Abstract
The paper is concerned with some digital-computer programs that were used in an experiment in automatic load dispatching. The problems of economic scheduling of generator outputs and assessment of the security of the supply network are discussed, and the programs used to solve them are described. The programs were adequate for experiments on automatic load dispatching, but experience has shown that they will need to be elaborated for use in a fully operational system. Some areas in which this elaboration will be necessary are listed.
