This paper presents an analysis of the behavior of an electricity market equilibrium model under a scenario with Large-Scale penetration of Wind Energy. The objective is to assess the robustness of this kind of models under the new context in which wind power is becoming increasingly important. In the model, different load level specifications are implemented as well as different scenarios of hydro conditions. The results show that the conjectural variation equilibrium model is robust to represent an electricity market with high penetration of wind energy.
