Abstract

With the growing use of wind power in power systems, the requirements of low-voltage ride-through (LVRT) have been proposed. Yet, all LVRT strategies commonly used in the doubly fed induction generator (DFIG) tend to change its running state, which brings a secondary impact to the transient stability of the system. This paper combines the output power of the DFIG with the equivalent mechanical power of the system, deducing the mathematical relationship between them, and theoretically analyzes the relationship between superconducting magnetic energy storage (SMES) access location and transient stability improvement. On this basis, this paper puts forward an SMES coordinated control scheme considering location information to improve the dynamic characteristics of grid-connected wind farm, achieving higher transient stability performance of the system. Finally, the simulation in MATLAB/Simulink verifies the effectiveness of the proposed control scheme. [ABSTRACT FROM AUTHOR]
