Abstract

One of the pillars in developing smart power systems is the use of load forecasting methods. In particular load forecasting accommodates decision making pertained to the operation of power market. In this paper, a new method for real-time updating very short-term load forecasting is proposed. The goal of the method is to accurately predict the load demand value in the next 5 minutes and accordingly update the daily forecast. To that end, the proposed method implements an ensemble of homogeneous learning Gaussian processes which are trained on slightly different training datasets. The predicted values are then fused using a fuzzy inference system in order to obtain a single value which is used to correct the precomputed forecast. The proposed method is tested on a set of real-world data taken from a major US area and is benchmarked against the naïve forecasting method. Results highlight the superiority of our method against the benchmarked method exhibiting an increase in forecasted accuracy by 50% in most cases.
