A new approach using artificial neural networks (ANNs) is proposed for short-term load forecasting. To forecast the hourly loads of a day, the hourly load pattern and the peak and valley loads of the day must be determined. In part I, a neural network based on self-organising feature maps to identify those days with similar hourly load patterns is developed. These days with similar load patterns are said to be of the same day type. The load pattern of the day under study is obtained by averaging the load patterns of several days in the past which are of the same day type as the given day. The effectiveness of the proposed neural network is demonstrated by the short-term load forecasting of the Taiwan Power Company
