With the adjustment of energy structure and the increase of uncertainty source load, the physical structure of the distribution network becomes more complex, and its intelligent and low-carbon operation face greater challenges. In addition, business and information flows of the distribution network have diversified and grown more complicated, placing more demands on the dispatching department's capacity for management and data collecting. It is challenging to evaluate the distribution network's overall operational status since its physical infrastructure and information system are continually being updated and changed. In order to meet the actual engineering needs and consider the intelligent development of the distribution network, it is important to build an evaluation system of the smart distribution network operation level from different dimensions. Firstly, a systematic analysis of the smart distribution network operation is carried out from three dimensions: physical, information and social, and an evaluation index system of the smart distribution network operation level is constructed. On this premise, a comprehensive evaluation method based on normal gray cloud clustering is proposed, and the distribution network development form is divided. Finally, the actual dispatching of the distribution network is used as an example to evaluate its current operation level, determine the division of the distribution network development form under each dimension, and provide path guidance for the balanced development of the smart distribution network.
