Comparison of Primary Frequency Support Methods for Wind Turbines
Paper i proceeding, 2013

This paper investigates and compares different methods of primary frequency control for wind power. The paper also identifies the models of hydro turbines and pitch regulated wind turbines. Short-term extra active power, inertia emulation and direct pitch angle regulation as a primary frequency control are evaluated when there is a power imbalance. In addition, the combinations of these three methods are evaluated. Simulation results show that the combination of temporary extra active power and inertia emulation method has the highest value of temporary minimum frequency. Although it is slower than other proposed methods and has second frequency drop. The advantage of using direct pitch angle regulation separately or in combining with the two other methods is that, the rotor speed does not decrease below the value that it has before the power imbalance happens.
