Design of fragile line identification method based on cloud edge collaboration
During the identification of fragile lines in power grid by using pure cloud computation,there are problems such as high computing pressure on main nodes and high time consumption.By introducing the cloud edge coordination method,a method based on cloud edge coordination for identifying fragile lines in power grid was designed.Based on the cloud edge collaborative logic architecture,cloud and edge computations were integrated to build a fragile line identification model.The PageRank algorithm was used to establish DNS cache and integrate edge device data sources under cloud computation.Based on Kirchhoff's law,the power flow values of different lines were calculated,and the identification of fragile lines was completed according to the power flow results.The results show that the as-proposed method has better performance and lower time consumption when identifying fragile lines in power grid.
