Fuzzy Evaluation Method of Integrated Energy System Based on D-S Evidence Theory under the Background of Energy Internet

With the popularization and application of technologies in the energy and power industry, the Energy Internet has shown more open and inclusive characteristics. In this paper, combined with the characteristics of integrated energy system evaluation, from the three dimensions of energy production, transmission and distribution, and consumption, established the corresponding evaluation index system. At the same time, determining the index weight based on the AHP-entropy method, and using the statistical evidence theory fusion cycle multiple evaluation results, avoids the influence of the transient and steady state conditions such as to improve the reliability of the evaluation results, forms a integrated energy system evaluation method based on evidence theory. Finally, this paper takes a park as an object to evaluate the operation level of the integrated energy system in this area.
