Load Forecasting is essential in planning and operation of power systems, in enlarging and reinforcing the basic network, is also very important commercially, valorizing the filing process of these data and extracting knowledge by computational techniques. Lately, several works have been published about electrical load forecasting. Short term, medium term and long term horizons are equally studied. The objective of this work is to present an electrical load forecasting system, which is simple and efficient and based on artificial neural networks whose training is with the back-propagation algorithm. Therefore, a software is developed using the paradigms of the object oriented programming technique to create a neural model which is ease to manipulate, and able to correct the local minimum problem. This system attributes the neural parameters automatically by exhaustive procedures. Results are compared with other works that have used the same data and this work presents a satisfactory performance when compared with those and others found in the literature. Key-words: Neural Network. Object oriented programming. Load forecasting. BackPropagation.
