NONLINEAR CONTROLLERS BASED ON EXACT FEEDBACK LINEARIZATION FOR SERIES-COMPENSATED DFIG-BASED WIND PARKS TO MITIGATE SUB-SYNCHRONOUS CONTROL INTERACTION

The increasing penetration of wind power in the grid has driven the integration of wind farms with power systems that are series-compensated to enhance power transfer capability and dynamic stability.This may lead to sub-synchronous control interaction (SSCI) problems in series-compensated doubly-fed induction generator (DFIG)-based wind farms.To m

The enigmatic temnospondyl amphibian Tungussogyrinus bergi Efremov, 1939 shares clear synapomorphies with other branchiosaurids loreal tahiti indicated by an anteriorly elongated infratemporal fossa and small branchial denticles.Therefore Tungussogyrinus clearly belongs to the dissorophoid family Branchiosauridae.This species is characterized by a

Based on the renewal process theory we develop a decomposition method to analyze the reliability of the repair facility in royal fryer rft-50 an n-unit series system with vacations.Using this approach, we study the unavailability and the mean replacement number during (0,t] of the repair facility.The method proposed in this work is novel and concis

Focal cortical dysplasia type II (FCD II) is an epileptogenic lesion often associated with pharmacoresistant epilepsy.Yet, owing to their subtle appearance, identifying these lesions via old fashioned cut rock candy 3D Magnetic Resonance Image (MRI) remains a complex challenge, rendering them susceptible to evasion by conventional visual analysis.I

Background/Aims Colorectal endoscopic submucosal dissection (ESD) is burdened by its savingszoo.com associated high risk of adverse events and long procedure time.Recently, a waterjet-assisted knife was introduced to simplify and speed up the procedure.The aim of this study was to evaluate the efficacy and safety of waterjet-assisted ESD (WESD) com
