“…In Farhadi and Tafreshi [27], SOM is used to classify normal and abnormal days, and a MultiLayer Perceptron (MLP) to manage temperature data. From a different perspective, Fan et al [28] use a particular method to forecast the price of electricity with SOM and SVM.…”

The adaptation of energy production to demand has been traditionally very important for utilities in order to optimize resource consumption. This is especially true also in microgrids where many intelligent elements have to adapt their behaviour depending on the future generation and consumption conditions. However, traditional forecasting has been performed only for extremely large areas, such as nations and regions. This work aims at presenting a solution for Short-Term Load Forecasting (STLF) in microgrids, based on a three-stage architecture which starts with pattern recognition by a Self-Organizing Map (SOM), a clustering of the previous partition via kmeans algorithm, and finally demand forecasting for each cluster with a MultiLayer Perceptron.Model validation was performed with data from a microgrid-sized environment provided by the Spanish company Iberdrola.

“…We propose efficient rules of Similar Sampling Process to train Kohonen neural network in the load forecasting models. According to these rules, each of the "normal week days", "official holidays", "before official holidays", "after official holidays" and "Ramadan days" have their own specific behaviors [13].…”

“…It is noteworthy that previous author's papers [13], [17] forecast the short-term (the next day) load, while the present paper focuses only on the method of classifying daily electric load and the classification of loads with the same behavior for the time period selected (e.g. one week, one month, or one year, or any desired time interval from one day to several years).…”

It is of vital importance to use proper training data to perform accurate shortterm load forecasting (STLF) based on artificial neural networks. The pattern of the loads which are used for the training of Kohonen Self Organizing Map (SOM) neural network in STLF models should be of the highest similarity with the pattern of the electric load of the forecasting day. In this paper, an electric load classifier model is proposed which relies on the pattern recognition capability of SOM. The performance of the proposed electric load classifier method is evaluated by Iran electric grid data. The proposed method requires a very few number of training samples for training the Kohonen neural network of the STLF model and can accurately predict electric load in the network.

It is of great significance to enhance the precision of power load forecasting for the security and stability of power system. According to the power load characteristics of both regularity and randomness, a novel load forecasting method based on the integration of similar load and recent historical load is proposed. In terms of similar load, this algorithm, firstly, utilizes matching coefficient of meteorological factors to quantify the similarity, then uses membership of day-type for the modification of similarity. After the process of filtering, the input sequence is made up of the combination of modified similar load and recent historical load. The results of simulation indicate that, compared with these forecasting algorithms merely based on similar load or on recent historical load, both mean relative error and mean square deviation of the algorithm presented in this paper are smaller and the precision of load prediction is higher.
