The Effect of Input Length on Prediction Accuracy in Short-Term Multi-Step Electricity Load Forecasting Using CNN-LSTM

This project investigates the effect of input sequence length on the accuracy of short-term multi-step electricity load forecasting using deep learning techniques. Using a real-world dataset from Panama's electricity consumption records, we implemented and compared the performance of four model: CNN-LSTM with Dense layers . This model is  evaluated for both hourly and daily forecasting to determine the optimal input configuration and architecture for high-precision predictions. CNN-LSTM model demonstrated superior performance and was selected for deployment. To enable practical usage, we developed a Flask-based web application with an intuitive front end using HTML, CSS, and JavaScript. After user login, the application allows users to input specific dates and receive accurate load forecasts along with interactive graphs. This system provides a reliable and user-friendly platform for electricity demand forecasting, supporting better planning and decision-making in energy management.
