How does variable wind generation affect primary frequency control?Increased variable wind generation will have many impacts on the primary frequency control actions of the power system. In , the lower system inertia was identified as one such impact because it would increase the requirements for primary frequency control reserves to arrest frequency at the same nadir following the sudden loss of generation.
How do wind turbines control primary frequency?The primary frequency control by wind turbines can be integrated into the rotor-side active power control loop and demonstrate behavior similar to conventional synchronous generators. The wind turbine must operate in curtailed mode to provide reserve for primary response when frequency drops.
What is the resonant frequency band range?However, considering the uncertainty of arm inductance, the high-frequency resonance band range of the system is significantly wider from 174 ∼ 193 Hz than the other two parameters; the entropy En and super-entropy He of the resonant frequency band are also the largest.
What factors affect the frequency response of wind power systems?The frequency response of such power systems will depend on many factors, including types and characteristics of conventional generation, their droop settings, the level of wind power penetration, etc. All conventional generation was set to operate with 5% droop and 0.036 Hz dead band. The wind turbines were set to operate with 5% spinning reserve.
Can a wind plant provide a governor response to low-frequency events?If the wind plant is also providing a governor response to low-frequency events, then the initial operation would be below the maximum power (curtailed operation) to provide primary reserves. In this case, there is more headroom for additional power increase when both inertial and governor controls are combined.
What are the factors affecting the resonance state?There are many uncertainties, like power equipment failure, random system responses, fluctuation of renewable energy, and transmission line parameter uncertainties resulting from high temperature or aging, etc. All the uncertain factors that can cause the impedance change of the system will shift the resonance sta
