Power system voltage security assessment is generally applied by considering the steady-state stability surface. However, as seen in the literature, random perturbations can drive the system away from stable operation, long before the steady-state stability surface is reached. In this article we include the value of the critical energy for the transient energy function, as a stability criterion when defining the stability boundary surface in parameter space. We show how the closest point on the surface of constant critical energy can be computed. The main contribution of this article is that it serves as a first step to include dynamic voltage collapse issues in the analysis of bulk power transfer security.
