Abstract

The growing involvement of alternative sources of clean energy to replace polluting sources in the energy matrix, aiming to reduce environmental impacts, has led to the expansion of wind power sources in the Brazilian electrical system. Wind power sources utilize wind turbines to convert the kinetic energy of air masses into electrical energy. However, fluctuations in wind speed and the intermittency of this type of source make it challenging to predict the operational scenario and can result in voltage instability issues. In this context, this work aims to present a methodology for representing voltage stability margins in this generation model. In this project, we will seek to understand and simulate situations that may compromise the system's stability. To achieve this, generation data will be analyzed, and a statistical method for dependency analysis and sampling will be used to create critical generation scenarios. Thus, the goal is to obtain a model that assists in the planning of electrical operation and safety analyses in power systems with a high penetration of wind power sources.
