Abstract:
Frequent flood disasters will lead to large-scale power outages in the distribution networks, and an effective resilience assessment system can help operation and maintenance personnels accurately predict and deal with distribution network failures caused by flood disasters and reduce economic loss. This paper proposes a three-dimensional resilience assessment index system, which consists of 12 individual indexes belong to state, architecture and time aspects. First, the influence of flood disaster on equipment failure rate is quantified and a mathematical model is established to reflect the relationship between rainstorm amount and failure rate. Then the fuzzy analytic hierarchy process (FAHP) and fuzzy membership function are used to comprehensively evaluate the resilience of the distribution network, and identify the weak links in the distribution network’s planning, operation and dispatching. Finally, a case study of Yubei district in Chongqing is carried out to verify the validity and rationality of the proposed resilience evaluation system.
