Abstract. The necessity to provide clean energy, along with the latest technology developments in the field of wind turbines, have been reflected by building bigger wind farms. This, combined with the integrated operation be-tween wind farms and the grid, involves all the electric sys-tem affecting different aspects as transitory stability, volt-age regulation, energy reserve management and the electric market. Most UE transmission system operators (TSO) have responded introducing technical regulations for wind farm interconnections. The present paper presents a com-parison of grid codes for wind farms (WF), and their op-erative implications. Key words Wind farm, grid code, connection requirements, voltage control, frequency control
