An Improved Control Strategy for DFIG Low Voltage Ride-Through Using Optimal Demagnetizing method

Crowbar With a Parallel RpLp Configuration Using PI Controller to Solve the Problem of DFIG-Wind Farm Stability During a Symmetrical Fault

“…To tackle the difficulties identified in literature regarding the use of the "crowbar with DC-chopper technique", it is proposed to employ an MPS technique. This technique enhances the DFIG's [11][12][13] ❖ Crowbar activation leads to a loss of control over the RSC.…”

“…To guarantee continuous network connectivity amidst disruptions, it's imperative for the system to incorporate fault ride-through (FRT) techniques that provide it with the capability to surmount faults. A plethora of distinct FRT methodologies have been suggested in existing literature and can be categorized as follows: the inclusion of supplementary protective mechanisms, such as the crowbar technique [11][12][13], crowbar with series dynamic braking resistors (SDBR) [14,15], and crowbar with DC-chopper [3,7,10,[16][17][18][19][20]; as well as the deployment of reactive power supply solutions like the static synchronous compensator (STATCOM) [21,22] and dynamic voltage restorer (DVR) [23].…”

An Intelligent Parameter Identification Method of DFIG Systems Using Hybrid Particle Swarm Optimization and Reinforcement Learning

“…The back-to-back converter can supply the rotor with currents of varying frequencies. The induction generator has the flexibility to import and export reactive power independent of the turning speed, enabling various ranges of speeds of wind turbines, thus providing high stability during severe disturbances [2]. The DFIG converter has lower costs and higher efficiency than other variable speed solutions.…”
