The increasing demand for low environmental impact energy sources has intensified the importance of renewable energy in many countries. Among them, wind farms have received strong incentives by the government and private agents and, consequently, have appeared every day more competitive and attractive. However, because of the operational characteristics of these power plants, which is characterized by a variability of the produced energy and the use of electronic converters, the interaction between wind farms and electrical network appears as a field of strong investigative interests. In fact, the issues related to the agreement with connection standards set by regulatory agencies, especially those concerning power quality and system dynamics have been considered challenging for successful operation of wind farms. In this context, this thesis focuses on establish a strategy to operative control of wind generation systems composed by full converters and synchronous machine, aiming at voltage control and harmonic current mitigation. This research includes activities related to the development of strategies, modeling, computational implementation and performance assessment to ratify the effectiveness of the proposals made.
