Frequency Activated Fast Power Reserve for Wind Power Plant Delivered from Stored Kinetic Energy in the Wind Turbine Inertia
With increased penetration of converter interfaced generation, synchronous generators may start to be displaced to keep the overall power balance. As a consequence the resulting inertia in the system may decrease and make the power system more exposed to frequency excursions. Here, a control is proposed that delivers a short-term power reserve from the kinetic energy in the wind turbine (WT) inertia, while considering the inherent characteristics of a wind power plant.
The aim is to contribute with a fast power reserve to stabilize the frequency drop during large and sudden production deficits until primary and secondary frequency reserves respond to restore the nominal frequency. A programmable reserve contribution in terms of amount and duration is proposed to be able to coordinate with other sources of frequency reserve.
Simulation results are shown for different WT operating points and response characteristics, which have a large impact on the subsequent recovery period.
