Power system integration of wind farms and analysis of grid code requirements

This paper covers the integration of the wind turbines with the national grids which includes the quality of the power generated at the wind plants, the impact to the power systems and the details of connection systems. The distribution system of Trakya area has been considered in detail together with Matlab software program. A power plant for 50 MW, which will be switched on in 2014, has been analyzed with its current situation and for the probably power capacity of 150 and 300 MW in the future. The impact to the national grid and the compatibility with current rules and standards has been checked by using different type of turbines. This praxis has been also repeated for the existing full scaled frequency inverted permanent magnet synchronous generators (PMSG), doubly fed asynchronous generators (DFIG) and fixed speed wind turbines.
