ANFIS-Fuzzy Logic-based Hybrid DFIG and PMSG Grid Connected System with TCSC

Abstract

Variable-speed wind turbines might provide green electricity. Grid operators’ grid regulations require wind turbines to recover from grid disruptions and help maintain electricity networks. Having wind turbines equipped with fault current limiters (FCLs) may ensure their continued functioning in the event of a power loss. In this piece, we will talk about how to improve the two most common types of variable-speed wind turbines: the Doubly Fed Induction Generator (DFIG) and the Permanent Magnet Synchronous Generator (PMSG). Both wind generators were evaluated using the Thyristor Controlled Series Compensator (TCSC) with ANFIS and Fuzzy Logic. It is important to understand the dynamic behavior of wind turbines, hence models of their FCLs were built for steady state and grid disruptions. Power interruptions switched the FCLs in both wind turbines utilising grid voltage variation. Both wind turbines underwent a no-control FCL scenario. Both wind turbines’ FCLs were measured and compared under load from a severe three-phase to ground failure at their terminals. Both wind turbines were operated under similar circumstances to examine FCL control tactics during power interruptions.
