• A differential protection technique for multi-terminal HVDC 

      Abu-Elanien, Ahmed E.B.; Elserougi, Ahmed A.; Abdel-Khalik, Ayman S.; Massoud, Ahmed M.; Ahmed, Shehab ( Elsevier Ltd , 2016 , Article)
      This paper presents a technique for differential protection of Multi-terminal High Voltage Direct Current (MTHVDC) transmission lines. The proposed technique depends on the electrical current data at both ends of each line ...
    • A Droop Control Design for Multiterminal HVDC of Offshore Wind Farms With Three-Wire Bipolar Transmission Lines 

      Abdel-Khalik, Ayman S.; Abu-Elanien, Ahmed E.B.; Elserougi, Ahmed A.; Ahmed, Shehab; Massoud, Ahmed M. ( IEEE , 2015 , Article)
      Converting existing ac transmission lines to an extended multiterminal three-wire bipolar HVDC system can be considered a cost-effective way to interconnect dispersed offshore wind farms to onshore ac grids instead of ...
    • A non-communication based protection algorithm for multi-terminal HVDC grids 

      Abu-Elanien, Ahmed E. B.; Abdel-Khalik, Ayman S.; Massoud, Ahmed M.; Ahmed, Shehab ( Elsevier Ltd , 2017 , Article)
      This paper introduces a non-communication based protection algorithm for Multi-Terminal High Voltage Direct Current (MTHVDC) transmission lines. The algorithm relies on using electrical current data at one end for ...
    • Design of Optimal Droop Control for Multi-Terminal High-Voltage Direct Current Systems During Line Outages 

      Abu-Elanien, Ahmed E. B.; Abdel-Khalik, Ayman S.; Massoud, Ahmed M.; Ahmed, Shehab ( Taylor and Francis Inc. , 2019 , Article)
      This article investigates the required modifications to droop control design for optimum operation of Multi-Terminal High-Voltage Direct Current (MTHVDC) systems during line and converter outages. A typical 6-bus MTHVDC ...
