    • A power control strategy for flywheel doubly-fed induction machine storage system using artificial neural network 

      Abdel-Khalik, A.; Elserougi, A.; Massoud, Ahmed; Ahmed, S. ( Elsevier Ltd , 2013 , Article)
      A large-capacity low-speed flywheel energy storage system (FESS) based on a doubly-fed induction machine (DFIM) consists of a wound-rotor induction machine and a back-to-back converter rated at 30-35% of the machine power ...

    • Digital control for UPS inverters 

      Ben-Brahim, Lazhar; Yokoyama, Tomoki; Kawamura, Atsuo ( IEEE , 2003 , Conference Paper)
      PWM inverters digital controls with dead-beat re sponse, for UPS applications, are reviewed. To improve the output waveforms of the PWM inverter, several modern control techniques are applied together with the deadbeat ...

    • Dynamic voltage restorer for voltage sag mitigation in oil & gas industry 

      Messiha, M.; Baraket, C.; Massoud, Ahmed; Iqbal, A.; Soliman, R. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)
      The objective of this paper is to design and implement an efficient and economical dynamic voltage restorer (DVR) to compensate for voltage sag conditions in oil and gas industry. In a power distribution system or plant ...
