It explores various protection strategies and techniques to enhance the wind energy systems' capability of withstanding low-voltage ride-through (LVRT) and reduce the total annual cost. The book addresses the advantages and disadvantages of each protection strategy, providing a comprehensive evaluation of the protection techniques employed to improve LVRT capabilities. The authors use the Al-Zafarana Wind Energy Conversion System as a case study system for simulation tests in a MATLAB/Simulink environment. Examines innovative and advanced solutions for integrating renewable energy sources into the electrical network; Looks at capabilities of grid-connected wind turbines and interconnection standards and international grid codes; Includes extensive case studies and examples with solutions. . 606 $aElectric power distribution 606 $aWind power 606 $aRenewable energy sources 606 $aElectric power production 606 $aPower electronics 606 $aEnergy Grids and Networks 606 $aWind Energy 606 $aRenewable Energy 606 $aMechanical Power Engineering 606 $aPower Electronics 615 0$aElectric power distribution. 615 0$aWind power. 615 0$aRenewable energy sources. 615 0$aElectric power production. 615 0$aPower electronics. 615 14$aEnergy Grids and Networks. 615 24$aWind Energy. 615 24$aRenewable Energy. 615 24$aMechanical Power Engineering. 615 24$aPower Electronics. 676 $a321.319 700 $aMahmoud$b Heba A$4aut$4http://id.loc.gov/vocabulary/relators/aut$01803215 702 $aA.
