Application of Time Series Prediction Models in Chinese Electricity Consumption Analysis

Abstract

Study focuses on the application of time series prediction models in analyzing electricity consumption in China, aiming to promote the intelligentization and sustainable development of the country's power system. The ARIMA model was chosen for this research, incorporating historical electricity data to forecast future consumption. Through a series of steps including data preprocessing, model construction, and prediction analysis, the results indicate a general growth trend in electricity consumption, influenced by seasonal and cyclical factors. By plotting periodic decomposition charts, the study visually reveals the components and patterns of electricity data, providing scientific decision-making support for the planning, scheduling, and management of the electricity industry.
