In this article, a critical and in-depth analysis is proposed regarding the applicability and limitations of classical power system models in the face of the increasing decentralization of the global energy matrix. Based on the fundamentals of circuit analysis, electromechanical energy conversion, and control theory, the investigation focuses on how the massive insertion of intermittent, inverter-based renewable sources challenges traditional concepts of angular, voltage, and frequency stability. The discussion addresses the imperative transition from controls based on physical inertia, typical of synchronous machines, to synthetic inertia strategies provided by advanced power electronics. The study revisits swing equations and stability criteria to demonstrate that, although network topology and equipment change, the underlying physics demands new adaptive control strategies and more sophisticated protection schemes. The conclusion points to the need for reengineering protection and control algorithms, grounded in a deep understanding of transient electromagnetic phenomena and rigorous mathematical modeling of static converters.
