Abstract :
A decoupled load flow for transient security studies is described, and a decoupled generator model for transient conditions derived. A modified susceptance matrix is defined as the Jacobian substitute. The method was tested on the IEEE 18- and 68-node systems, showing fast convergence, and that the necessity for Jacobian refactorizations was radically reduced
