Over de invloed van het weer op electriciteits maxima en verificatie van schattingen dezer maxima gedurende de periode 1 januari 1972 - 1 januari 1983 in Zuid Holland

This paper contains an analysis of the weather effects on the peak loads of the electricity power system in the South West of the Netherlands.There is no economical means of storing electrical energy on a large scale and hence It is necessary to load and unload in strict accordance with the rise and fall of demands of the consumers. Weather conditions have a large effect on this demand especially during the peak-hour periods.The peak loads of the working days from the period 1972-1982 have been related to meteorological parameters i.e. the condition of the sky (degree of cloudiness) and the temperature. A further selection of parameters e.g. windvelocity and precipitation was abandoned because of the lack of sufficient data. The relationship was established after elimination of the effects of non-meteorological parameters, i.e. long-term trend, seasonal variations and character of the day.
Using a semi-objective method (developed from earlier data in the same way) load estimates for the period 1972-1982 were made daily. These estimates, which are highly dependent on accurate forecasting of the weather, were verified and the results of the verification are summarized in part 4. The mean deviations of the errors in the daily load forecasts amounted to 28.0 Mw (24h forecasts) and 20.6 Mw (8h forecasts) corresponding to 1.7% and 1.3% of the mean load.It is noteworthy that the literature about load-dispatching is now more scarce than it was 35 years ago and we never saw a systematic verification of load estimates.
