An Evaluation of Flux-Coupling Type SFCL Placement in Hybrid Grid System Based on Power Quality Risk Index

摘要: Due to the expansion of restructured electricity markets and consequently power network operation approaching dynamic static margins, probability transient instability has remarkably been increased. To reduce risk or probabilistic cost quality, present study focuses on determining optimum location a flux-coupling type SFCL. this end, candidate locations with lower related are selected as best for installing SFCLs. Nowadays, SFCL employed in study, which enjoys benefits both resistive inductive SFCLs, is suitable means enhancing stability electrical grids. Despite being another useful approach evaluation, equal-area criterion merely restricted analysis single-machine system connected an infinite bus also two-machine system. The online based corrected energy margin (CTEM), some factors, instability. Furthermore, CTEM index tool calculating critical clearing time (CCT). Therefore, recent years, become more useful. studies carried out IEEE New England 39-bus test ascertain high applicability proposed method.
