چکیده

Nowadays, propagation of wind turbines make challenges to supply safe power to the grid. Because of wind speed changes, supervisors are concerned to wind turbines, be able to produce appropriate electric power during the wind speed changes. As a matter of fact, investors are mostly like to invest on offshore wind farms, because of their more stable and continuous wind speed rather than onshore ones. Although offshore wind farms are more reliable than onshore ones, their power control is a very important issue. In this paper a method is presented to control wind farms output power. This method is able to fix wind farm output power even during the wind speed changes. On the other hand by this method, the wind farm is able to operate such as a PV BUS. The proposed wind farm configuration and control system is validated by simulation on Matlab/Simulink software. We also formulate and model the wind turbine, VSC converters of HVDC link and the PMSG generator. Moreover they are modeled and simulated on d-q frame by MATLAB/Simulink.
