【 摘 要 】

Recently, the integration of DG (distributed generation) with high penetration and new loads lead to the transformation to active distribution network. Thus, it is necessary to propose a more suitable comprehensive evaluation index system to achieve the scientific evaluation of operation state and the development of active distribution network. This paper presents a new comprehensive evaluation index system for the active distribution network considering the influence of DG and new load. The combined weighting method based on the variable weight theory and the multi-layer fuzzy comprehensive evaluation method based on the improved trapezoidal cloud model is proposed to solve the model. Finally, case study is carried out to verify the validity of the proposed method and provide the reference value for the future development of distribution network.
