摘      要：This paper reviews the effects caused by a high penetration of wind farms on network frequency. Energy generation in wind farms that use induction generators (as installed in Manjil Power Plant) is simulated, and, assuming that wind farm units provide 10% of the network power, the effect on frequency is studied, and it is shown that such a high penetration of the wind farms has a destructive effect on network frequency. It will be shown that the negative effects can be compensated for by using stored energy, but in the absence of energy storage equipments like SMES (Super Magnetic Energy Storage), this solution is beyond reach. An alternative method is presented that is based on Rotary Frequency Converter (RFC), and, as can be seen in the simulations, the wind farm output creates fewer disturbances, and frequency variations can be controlled considerably.
