Abstract: This paper introduces the technical background and related technical means for realizing power load forecasting based on intelligent technologies. The intelligent technologies mainly refer to artificial intelligence,big data,and other technologies. It focuses on analyzing the relevant technologies for realizing power load forecasting based on artificial intelligence or big data by relying on the Himmpat patent database. Starting from aspects such as global patent application trends,application layouts of major source countries,technological layouts of major global applicants,and global patent legal status,the R&D focuses of power load forecasting based on intelligent technologies at home and abroad are revealed. Furthermore,relevant suggestions for the development of this technology are put forward,providing valuable references for the relevant research in enterprises and universities,so as to better promote the sustainable development of power load forecasting technology.

Key words: intelligent technologies, artificial intelligence, big data, patent, power load forecasting
