Electromechanical transient analysis considering the effects of wind turbines connected to the network

The diversification of the energy supply associated with the increasing interest in clean energy sources make most of the countries seek new technologies that could meet these needs. In this way, there has been a large increase in the number of wind turbines connected to the network. Considering the technological development and consequent increase in their capacity, the impact of wind turbines upon the network has been considered increasingly important for both steady state and dynamic conditions. In view of that, this paper will present a dynamic analysis of the impacts, especially electromechanical transients, caused by doubly-fed induction generator (DFIG) based wind turbines connected to the transmission electrical system.
