Description

technical field [0001] The invention relates to the technical field of abnormal value detection in a comprehensive energy system, in particular to a method and device for detecting abnormal value of a comprehensive energy load. Background technique [0002] With the rapid development of energy Internet technology, users' demand for energy has exploded. The comprehensive energy load data as a whole shows the characteristics of mass, diversity and rapid growth. The quality of comprehensive energy load data has a very important impact on the stable operation and real-time analysis of the entire system. However, in actual production and life, the massive data collected by the user side will generate a large amount of abnormal load data due to the failure of its own equipment or the influence of external environmental factors. Therefore, in order to improve the safety and reliability of the operation of the integrated energy system, it is of great significance to accurately and...
