Power quality measurements and analysis for Zhong-Tun Wind Farm in Penghu

The wind resource in Penghu is abundant. According to the operating experience and generation output from the Penghu´s Zhong-Tun Wind Farm, the capacity factor is above 47%. Currently, the total installed capacity of wind turbines in Penghu reached 10.2 MW and the highest penetration of wind power can be reached 35%. Therefore, such a high penetration of wind power may impact the power quality, grid operation, and transient characteristics of Penghu´s power system. In order to obtain a complete picture of power quality in the high wind penetration system in Penghu, this work analyzes the one-year measurement data for Penghu Zhong-Tun Wind Farm. These measurements include active power, reactive power, power factor, frequency, voltage, current, harmonic, flicker, voltage variation, and voltage unbalance. This work gives an important reference on the power quality issue under a high wind power penetration environment.
