The Power System Toolbox (PST) is a MATLAB-based package for simulating power system electromechanical dynamics. In this paper, we report on code that we developed to augment the capabilities of the PST, which enables the possibility of including the automatic generation control (AGC) system in simulations. In the process, we have also modified the linearization capability of the PST so as to include the effect of the AGC system when enabled in the simulation. The augmented PST package can be easily utilized for simulation studies in different applications. As an example, we focus on its utilization for assessing the impact of cyber events on power system dynamic performance. Specifically, by using the augmented PST package, users can inject various measurement errors and communication delays to signals that are used by the AGC system, and simulate the effect of such cyber events on system dynamic performance. We present several case studies to illustrate the new features added to the PST.
