Testo completoPower systems are evolving significantly due to economic, geopolitical, and environmental factors, notably the increasing integration of Renewable Energy Sources (RES) interfaced through power electronic converters, known as Inverter-Based Resources (IBR). This shift from synchronous machine (SM)-dominated systems to IBR-dominated systems introduces challenges such as reduced inertia, intermittency, and stability issues. Traditional stability analysis and modeling techniques, which assume slower dynamics inherent in SMs, are inadequate for the fast dynamics of IBRs. The emerging dominance of IBRs necessitates the development of detailed Electromagnetic Transient (EMT) models, which are computationally intensive but essential for capturing the fast dynamics of modern power systems. Existing stability classification frameworks, historically based on SM-dominated systems, are being revised to incorporate IBR influences, introducing new stability categories like Converter-Driven Stability (CDS). This work investigates novel insights into the interactions between SMs, IBR unit dynamics, and network dynamics that have been overlooked in the literature. It provides a comprehensive framework that is open-source and adaptable for generic power system topologies, allowing for scalable results and analyses. Furthermore, the proposed framework is utilized to determine optimal allocations of virtual inertia and damping in low inertia power systems to enhance frequency stability metrics

Testo completoPiecewise affine hybrid systems are an important and simple class of hybrid dynamical systems. A piecewise affine system is composed of several dynamical affine subsystems and of switching rules that decide the behavior of the active subsystem during each switching interval. Recently, it has been shown that this class of systems is very rich in nonlinear phenomena such as bifurcations and chaos. Piecewise affine hybrid systems arise in many engineering applications such as DC-DC converters. Modeling of such converters is given using classical averaged or discrete models. However, a possible approach to analyze these circuits can be done using hybrid models. The behavior of a hybrid system is based on events' existence. Simulation which is a simple tool to analyze these systems, requires an algorithm that gives exact switched dates. Existing detection techniques, that are essentially based on approximated schemes, may lose some events and then diverge drastically from the real trajectory of the simulated hybrid system. Our aim within this thesis is to provide a fast and accurate simulation tool of 2nd order planar piecewise hybrid systems, which is based on analytical expressions of solutions. Our semi-analytic approach gives switching instants of state event and periodic temporal events. Our algorithm is implemented in a Scicos toolbox, another alternative in Matlab is also available
