Linear Model for Dynamic Studies of Power System Frequency

The ongoing progressive reduction of the system inertia is posing several engineering challenges. This new scenario is very challenging for the frequency control of the power systems and requires suitable dynamical models and analysis tools. The available, well known, engineering tools for modeling and simulation of power systems are not very suitable for control and optimization purposes. This paper describes the developing of a new modeling tool that, departing from power flow and dynamic information in PSS/E format, builds a linear multi-variable model able to be used for control and optimization purposes. The general mathematical structure of the model is thoroughly described as well its application to a classical IEEE benchmark.
