Research on digital twin-based reliability evaluation of electric power optical communication network

The reliable and stable operation of Electric Power Optical Communication Network (EPOCN) is the basis for the optimization of distributed energy management. How to evaluate the operation reliability of EPOCN devices and carrying reliability remains a challenge. In this paper, we firstly propose a digital twin-based two-dimensional multi-level reliability assessment indicator system of EPOCN, which consists of device reliability and service reliability. Secondly, an improved fuzzy hierarchical reliability assessment method for EPOCN is proposed to assess the reliability level of EPOCN by scoring each level. Finally, an example is given to verify the superiority of the proposed technique in reliability indicator processing, which can effectively reduce the influence of subjective factors of evaluators and objectively reflect the reliability of EPOCN.
