Flow betweenness
WebThe current-flow betweenness of a vertex v is defined as the amount of current that flows through v in this setup, averaged over all vertex pairs s and t. The current-flow betweenness of a vertex v is the average of the current flow over all source–target pairs: where n (n − 1)/2 is a normalizing constant, and I v(st) is the current flow ... WebNov 1, 2015 · Abstract. It is an important part for the power system operation risk control to identify the critical lines. To improve the identification accuracy, the indicator of active power flow betweenness ...
