Line differentiation planning of distribution network considering weaknesses assessment of resilience

Differentiation planning reasonably has instruction function for strengthening the construction of the distribution network structure with pertinence, as well as improving the ability of withstanding natural disasters. A method of differentiation planning of distribution network structure was proposed, based on its weaknesses. Aimed at the situations of natural disasters and important consumers, network reconfiguration with the objective to minimize the load shedding was used to search for the post-disaster structure. After that, the assessment of economy and resilience index were applied with planning, the optimal planning was determined with the operation method of technique for order preference by similarity to an ideal solution (TOPSIS). By the analysis of example, the resilience assessment of structure weakness plays a conductive role of differentiation planning on distribution network.
