On the Electromechanical Energy Approach: A Novel Modeling Method for Power Systems Stability Studies

This paper presents a novel modeling method for assessing power system oscillatory modes with the aim at further controllers' design. The method is denominated Electromechanical Energy Approach since it regards the idea of mechanical rotating bars to represent each node of the power system. The main difference between the presented method and others lies on the fact that the Eletromechanical Energy Approach regards intrinsically the voltage dynamics of system's nodes, i.e., both mechanical and electrical dynamics are obtained inherently. Besides, this approach reduces model's complexity and allows a better fitting for system's oscillation modes, both very welcome features whenever one wants an accurate and feasible model for designing power system controllers.
