Abstract: To address the increasingly complex operational risk challenges faced by distribution networks with high-penetration renewable energy integration, this paper proposes a multi-hierarchy risk assessment method for distribution networks covering the transformer district-feeder-substation levels. Firstly, a multi-dimensional risk evaluation index system incorporating multi-time scales is established. Secondly, a combined weighting model integrating the entropy weight method and analytic hierarchy process is introduced to comprehensively consider subjective and objective information and scientifically determine the index weights. On this basis, a systematic multi-hierarchy risk assessment process and quantitative calculation method are put forward. Finally, the effectiveness of the proposed method is verified through practical case studies. The results show that this method can accurately identify risk weak points at different levels, and the assessment results are more comprehensive and reasonable, which can provide a quantitative basis for the hierarchical and targeted risk prevention, control, and operation and maintenance decision-making of distribution networks.
