Abstract

In Weather-aware forecasting method for the household electricity demand was developed based on real electricity consumption and climatological data in a small community located in Mexico. Analysis was conducted on the electricity-level records of the households with the relevant outdoor weather variables such as temperature, humidity, solar radiation, wind speed, rain fall, pressure etc. These methods included time-series preprocessing, lag feature construction, descriptive analysis, correlation assessment and comparative forecasting models to analyze the behavior of the demand and forecasting accuracy. Results revealed an obvious difference in household electricity usage across the hours, with higher demand for electricity in the evening hours. There is significant contextual value in the weather variables, but the strongest predictor was lagged electricity demand, which also worked well in nonlinear models. The weather-sensitive random forest model outperformed the other models and the persistence baseline, with gradient boosting closely behind. The results confirm that using these temporal demand features alongside some of the weather parameters selected will increase the accuracy of electricity forecasting and enable practical energy planning, anticipating peak demand, and managing residential demand in response to the weather.
