In previous work,we applied artificial neural networks (ANN) for short term load forecasting using real load and weather data from the Hydro-Quebec databases where three types of variables were used as inputs to the neural network:(a) hour and day indicators,(b) weather related inputs and (c) historical loads.In general,for forecasting with a lead time of up to a few days ahead,load history (for the last few days) is not available,and therefore,estimated values of this load are used instead.However,a small error in these estimated values may grow up dramatically and lead to a serious problem in load forecasting since this error is fed back as an input to the forecasting procedure.In this paper,we demonstrate ANN capabilities in load forecasting without the use of load history as an input.In addition,only temperature (from weather variables) is used,in this application,where results show that other variables like sky condition (cloud cover) and wind velocity have no serious effect and may not be considered in the load forecasting procedure.
