DFIG-Based rotor kinetic energy: Using adaptive droop control strategy
Proceedings of the 2023 7th International Conference on Electronic Information Technology and Computer Engineering, 2023Aiming at the problem that the existing DFIG frequency control strategy fails to fully exploit the rotational kinetic power, and it is easy to cause a secondary decrease in the frequency of the grid in the speed recovery stage, a variable domain fuzzy ...

Vector control strategy for PMSM using rotor kinetic energy
2016 IEEE 11th Conference on Industrial Electronics and Applications (ICIEA), 2016An energy exchange relation of the permanent magnet synchronous motor control system is analyzed firstly. Then a novel control strategy using the rotor kinetic energy is proposed. A load estimation method is put forward for the load and inertia ripple. The simulation and experiment results demonstrate the effectiveness of the proposed control strategy ...

System Inertia Support from a Wind Farm Using Rotor Kinetic Energy-Based Varying Droop Control
2020 IEEE/IAS Industrial and Commercial Power System Asia (I&CPS Asia), 2020Available rotor kinetic energies from doubly-fed induction generators (DFIGs) in the upstream of a wind farm are different from DFIGs in the downstream due to the non-negligible wake effect. Thus, a variable gain of a droop control method is required for system inertia support because the constant-control gain method weakens the inertia support ...

Homopolar Active Magnetic Bearing Design for Outer Rotor Kinetic Energy Storages
2019 IEEE International Electric Machines & Drives Conference (IEMDC), 2019For high speed kinetic energy storage systems in outer rotor topology, active magnetic bearings play a major role in enabling high energy efficiencies and energy densities. The outer rotor setup enables the use of a soft magnetic composite on the rotor, which in turn facilitates the use of homopolar magnetic bearings.

Kinetic Energy based Rotor Speed Control for the PMSG-WECS Considering the losses
2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019Based on the system kinetic energy, a rotor speed control considering system losses is proposed for the permanent magnet synchronous generator wind energy conversion system (PMSG-WECS). The sub-optimal power point of the PMSG is tracked to output the relative smoother power by comparing with the maximum power point tracking (MPPT) control.
