Kinetic Energy of Wind-Turbine Generators for System Frequency Support

As wind power penetration increases and fossil plants are retired, it is feared that there will be insufficient kinetic energy (KE) from the plants to support the system frequency. This paper shows the fear is groundless because the high inertias (H congruent to 4 seconds) of wind turbine-generators (WTGs) can be integrated to provide frequency support during generation outage.
