ABSTRACT

FIGURE VI.5.6 Absolute percentage error for the maximum daily load. Period from February 15 to July 31, 24 weeks. Upper curve: neural forecaster; lower curve: operator. The peak error is for Easter holidays. (From Sfoma, M. and Proverbio, F., Electric Power Syst. Res., 33(2), 139, 1995. With permission from Elsevier.)

put into daily operation, a comparison with the operators' performances during the same period of time was made. In Figure VI.5.6, the two curves represent the average absolute percentage error for the maximum load, both for the neural and human forecaster (e.g., the values of the upper curve are listed in the first column of Table VI.5.1).
