This paper presents the relationship between a detailed power system dynamic model and a standard loadflow model. The linearized dynamic model is examined to show how the load-flow Jacobian appears in the system dynamic state Jacobian for evaluating steady-state stability. Two special cases are given for the situation when singularity of the load-flow Jacobian implies singularity of the system dynamic state Jacobian.
