Development of online load-prediction techniques with results from trials in the south-west region of the CEGB

The application of a statistical method to the problem of online load prediction is described. The method was implemented as part of an automatic load-dispatching program for the control of a power system. Although offline tests gave satisfactory results, it was found that the method was adversely affected by measurement errors greater than expected when applied on line. An alternative scheme was developed to overcome this difficulty. Numerous results concerning the accuracies of both methods are presented.
