Reactive planning considering Offshore Wind Power generation

Nowadays, the penetration of wind power in power systems increases very fast. In particular, the Offshore Wind Farms (OWFs) are very promising for future development. The unpredictable real output of the Wind Farms (WF) can cause reactive power problems and lead to variable voltage profiles and consequently to voltage quality issues. Given these circumstances, this paper presents a summary of the main issues related to the Reactive Power Planning (RPP) stage of new OWFs and their connections. Thus, first the wind turbine generators types are described, emphasizing on their reactive output characteristics. Then, the major transmission technologies that can be used to connect the wind farms to the grid are reviewed. In the last part, a possible RPP models are given. With reference to the particular aspects related to the wind farms and the connection solutions.
