The Application of Uncertainty Algorithm in Electric Power System

There are many fuzzy problems in the power system, such as fault diagnosis, condition assessment, etc. Despite the rapid development of science and technology, uncertain and incomplete information still exists to varying degrees. These problems of ten involve multiple factors. It is very important to choose a suitable method to deal with such problems. In this paper, a new uncertainty algorithm is proposed based on fuzzy theory, rough set theory and evidence theory to solve the problem of multi-index uncertainty in power system. This algorithm can process inaccurate data and then analyze it. Taking the transformer state evaluation as an example, the application of this algorithm is illustrated.
