ESO-Based Inertia Emulation and Rotor Speed Recovery Control for DFIGs
IEEE Transactions on Energy Conversion, 2017In recent years, with the ever increasing penetration of wind generation, great concerns have been raised since the constantly decline of system's inertia may considerably deteriorate the frequency stability of power system. In this regard, an inertial response control technique is proposed to enable wind generators to provide the power system with ...

2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia), 2020
The increasing amount of variable speed wind turbines (VSWTs) is witnessed by modern power systems. However, this high-penetration level of wind energies leads to the reduction of power system inertia. To solve the lack of inertia issue, releasing the kinetic energy stored in the rotating masses of Permanent Magnet Synchronous Generator (PMSG)-coupled ...

Abstract The theory about how to calculate the rotor speed for a self-driven rotary energy recovery device has been investigated by methods of computational fluid dynamics simulation and validating experiments in this paper. Rotor speed can be obtained according to impulse torque of the rotor and its frictional resistance.

Traditional grid-following virtual inertia control wind turbines (WTs) typically achieve rotor speed protection (RSP) and recovery (RSR) through adjusting coefficients. However, for grid-forming (GFM) virtual synchronous generator (VSG) controlled WTs, due to the coupling between parameters and damping characteristics, the adjustment range is limited ...
