    • Active Power Filter 

      Massoud, Ahmed M.; Ahmed, Shehab; AbdelKhalik, Ayman S. ( John Wiley & Sons, Ltd , 2014 , Book chapter)
      The proliferation of power electronics-based devices and equipment has significantly affected the power quality of the grid, which changes its sinusoidal nature through adding harmonic distortion. Power electronics ...

    • Flywheel Energy Storage Systems 

      Daoud, Mohammed; Abdel-Khalik, Ayman; Elserogi, Ahmed; Ahmed, Shehab; Massoud, Ahmed ( John Wiley & Sons, Ltd , 2015 , Book chapter)
      Flywheels are one of the oldest and most popular energy storage media owing to the simplicity of storing kinetic energy in a rotating mass. Flywheel energy storage systems (FESSs) can be used in different applications, for ...

    • GridConnected CapacitorTapped MultiModule Voltage Source Converter 

      Elserougi, Ahmed Abbas; Ahmed, Shehab; Massoud, Ahmed ( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)
      In this work, a new dc-ac converter is proposed for grid integration purposes, namely, capacitor-tapped multi-module dc-ac voltage source converter. The main advantages of the proposed converter when compared with the ...

    • Maximum Power Transfer Of Pv-fed Inverter-based Distributed Generation With Improved Voltage Regulation Using Flywheel Energy Storage Systems 

      El Deeb, Hisham; Massoud, Ahmed; Abbas, Ahmed; Ahmed, Shehab; Abdel-khalik, Ayman; ... more authors ( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)
      One of the main issues accompanied with the high penetration of PV distributed generation (DG) systems in low voltage (LV) networks is the overvoltage challenge. The amount of injected power to the grid is directly related ...
