Given the current challenges of power system operation, the objective of this research project is to contribute with the difficult problem of developing techniques for real time assessment of the dynamical security of electrical power systems. The increasing level of uncertainties in the operation of power systems, mainly due to the rapidly growing insertion of renewable and non-conventio…
This proposal aims the creation of a National Institute of Science and Technology to deal with cooperative autonomous systems (INCT- SAC). Motivated by Brazil’s large territory and population size, wide-ranging geographic features, and economic and social issues, we intend to solve problems related to security and environment. This INCT will address some of these challenges by proposing n…
The visiting researcher will collaborate on two research projects with the responsible researcher, namely: Avaliação de Segurança Dinâmica de Sistemas Elétricos de Potência: Estabilidade de Ângulo e Tensão, supported by CNPq, and Distributed Coordination for a Smarter and Sustainable Power Grid, supported by NsF. Both projects are on the general trust area of increasing the Smart Grids se…
The main goal of this research project is the development of direct methods for real time analysis of electrical power systems subjected to large perturbations, including the problem of transient stability (or rotor angle stability) and voltage stability. Direct methods allow the fast assessment of stability of large electrical power systems and are fundamental to the development of dynam…

The search for alternative sources of clean energy which are capable of substituting polluting sources , seeking the reduction of environmental damage, has resulted in the growth of wind power sources. This type of energy source utilizes massives wind turbines in order to convert the air masses' kinetic energy into electrical energy. However, intrensic variations to the wind´s velocity , …
The increase in demand of electrical energy of the current Electric Power Systems (EPS) forces them to operate closer to their limits. Therefore, it is becoming increasingly necessary the research and implementation of safety analysis tools to ensure the stable operation of these systems in the face of load variations. In addition, in the current EPSs, there is a penetration increase of i…
With the continuous growth of load, Electric Power Systems (EPS) began to operate closer to its limits. Consequently, the importance of implementing dynamic safety assessment tools in the real-time operating environment has increased. In the context of safety assessments, we have the problem of voltage stability assessments by the characterization of the Load Margin (LM), which relates th…
This project's purpose is to develop the foundations of the theory of the stability region of nonlinear dynamical systems in discrete time. In particular, it aims to develop a complete characterization of stability region and its boundary, extending the existing results of continuous systems for a class of nonlinear dynamical systems in discrete time. It is expected that the results can p…

The number of Electrical Power Systems (EPSs) that have voltagestability issues as their main security threat has been increasing over recentdecades. Estimating the loading margin has become highly importantand many methods have been proposed to measure the distance toSaddle-Node Bifurcation (SNB). However, generators over excitation limitersmay cause structure induced bifurcations (SIB),…
In the current state-of-the-art, the Two-Time Scale (TTS) CUEP/BCU method takes advantage of the existence of fast and slow time scales in the power systems mathematical models in order to decompose CUEP calculations in direct transient stability analysis into the CUEP calculation of the slow and fast subsystems. However, the TTS-CUEP/BCU method was demonstrated for power system models co…
