With the development of Advanced information technology in distribution network, it is of great significance to study the distribution network cyber physical system (DNCPS) and its vulnerability assessment method to ensure the safety and stability of power grid. To accurately evaluate the vulnerability of communication nodes in DNCPS, a hierarchical DNCPS model is established based on the actual structure of the distribution network. By analyzing multiple factors including node topological structure, invalid probability, and business type, a multi-level vulnerability assessment system for communication nodes is proposed. The randomized analytic hierarchy process (RAHP) combined with the technique for order of preference by similarity to ideal solution (TOPSIS) is used to validating the effectiveness of the evaluation method through case studies.
