Modelagem e análise dinâmica de um parque eólico dotado de geradores DFIG em uma rede de subtransmissão usando PSCAD/EMTDC

Abstract

The growing concern about climate change and the need to reduce global greenhouse gas emissions have driven a profound transformation in the global energy sector. In this context, wind energy has become one of the main renewable alternatives, combining technological maturity, economic competitiveness, and low environmen tal impact. Although wind power contributes to the diversification of generation sources, it also introduces new technical challenges related to system stability and power quality, requiring the improvement of grid integration standards and models. In this scenario, the present study is motivated by the increasing participation of wind energy in both the global and national energy mix, which demands a deeper understanding of the dynamic behavior of generation systems and their interac tion with subtransmission networks. This work aims to analyze the performance of wind farms composed of Doubly Fed Induction Generators (DFIG) connected to the electrical grid, through modeling and simulations in the PSCAD/EMTDC environment, contributing to the understanding of transient phenomena associated with wind power operation and providing technical insights to enhance the stabi lity, control, and reliability of the integration of these renewable sources into power systems.
