摘要
Abstract
To better reveal the characteristics of the power grid with its complexity and identify the key parts that may trigger a large-scale accident within the grid,the existing power grid complex network model is improved by the definition of power transmission path,weighted power transmission distance and path transmission capability,which now complies with the basic electrical law of power grid and the physical constraints.Based on the improved power grid complex network model,an evaluation index set of the key bus and branches within the grid is established,including indices of distance degree,capability degree,hub betweenness,distance betweenness and capability betweenness,which fully considers the variety of tasks that each and every key bus and key branch undertake in the grid structure and operation.Simulations of both IEEE typical test system and Hubei power grid are conducted using the proposed model and algorithm,with key parts identification yielding good results.In comparison with some existing methods,the rationality and effectiveness of the proposed algorithm are verified.关键词
