    • openAccess   A multilevel modular dc-dc converter topology 

      Vidal-Albalate, Ricardo; Soto Sánchez, Diego; Andrade, Iván; Riedemann, Javier; Pesce, Cristián; Belenguer Balaguer, Enrique; Peña, Rubén; Blasco-Gimenez, Ramon Elsevier (2017)
      A multilevel modular DC-DC power conversion topology based on cascaded H-Bridge converters in a double П configuration is presented. The topology is intended to interconnect large power DC networks. A two level control ...

    • openAccess   Analysis of the Performance of MMC Under Fault Conditions in HVDC-Based Offshore Wind Farms 

      Vidal-Albalate, Ricardo; Beltran, Hector; Rolán Blanco, Alejandro; Belenguer Balaguer, Enrique; Peña, Rubén; Blasco-Gimenez, Ramon Institute of Electrical and Electronics Engineers (IEEE (2016-04)
      This paper analyzes the behavior of a modular multilevel converter-high-voltage direct-current (MMC-HVDC)-connected offshore wind power plant (WPP) during dc faults. For that purpose, detailed models of the dc cable, ...

    • openAccess   Automatic under-frequency load shedding mal-operation in power systems with high wind power penetration 

      Aparicio, N.; Añó-Villalba, Salvador; Belenguer Balaguer, Enrique; Blasco-Gimenez, Ramon Elsevier (2017)
      Countries with a limited interconnection capacity suffer substantial frequency variations after large incidents so they use automatic under-frequency load shedding schemes to arrest the frequency decay. Some of these ...

    • openAccess   Efficient model for modular multi-level converter simulation 

      Vidal-Albalate, Ricardo; Belenguer Balaguer, Enrique; Beltran, Hector; Blasco-Gimenez, Ramon Elsevier (2016)
      Detailed models of modular multi-level converters (MMCs) are cumbersome for electromagnetic transient simulation programs because of their high number of components which involve large simulation times. In this work, the ...

    • openAccess   Embedded Real-Time Simulator for Sensorless Control of Modular Multi-Level Converters 

      Tormo, Daniel; Vidal-Albalate, Ricardo; IDKHAJINE, LAHOUCINE; Monmasson, Eric; Blasco-Gimenez, Ramon MDPI (2022-02-25)
      This paper suggests the application of an embedded real-time simulator (eRTS) in the context of voltage–sensorless control of a modular multilevel power converter (MMC). This eRTS acts as an observer and ensures digital ...

    • openAccess   LCC-HVDC Connection of Offshore Wind Farms With Reduced Filter Banks 

      Blasco-Gimenez, Ramon; Aparicio, N.; Añó-Villalba, Salvador; Bernal-Pérez, S. Institute of Electrical and Electronics Engineers (IEEE) (2013)
      Despite being more efficient, line commutated converter-HVDC links for the connection of large offshore wind farms have ac-filter bank size as one of their main drawbacks. This paper shows how the HVDC rectifier filter ...

    • openAccess   Protection Strategies for the Connection of Diode Rectifier-Based Wind Power Plants to HVdc Interconnectors 

      Martínez-Turégano, J.; Vidal-Albalate, Ricardo; Añó-Villalba, Salvador; Bernal-Perez, Soledad; Blasco-Gimenez, Ramon Institute of Electrical and Electronics Engineers (2020-10-05)
      The connection of diode rectifier (DR)-based wind power plants (WPPs) to existing or planned high-voltage dc (HVdc) interconnectors can lead to important savings on cost and system robustness. Since the DR station usually ...

    • openAccess   Sizing and Short-Circuit Capability of a Transformerless HVDC DC-DC Converter 

      Vidal-Albalate, Ricardo; Soto Sánchez, Diego; Belenguer, Enrique; Peña, Rubén; Blasco-Gimenez, Ramon Institute of Electrical and Electronics Engineers (2020-01-15)
      This work aims at optimizing the converter design of the double-T MMC DC-DC converter in terms of transmitted power per submodule and also in terms of transmitted power per silicon area, while, at the same time, providing ...

    • closedAccess   Wind power plant integration in voltage source converter HVdc grids with voltage droop control 

      Añó-Villalba, Salvador; Blasco-Gimenez, Ramon; Bernal-Pérez, S.; Belenguer Balaguer, Enrique Elsevier (2018)
      This paper introduces the use of a diode-based HVdc rectifier for the integration of a large off-shore wind power plant into an existing HVdc voltage source converter-based grid. The proposed control system allows for the ...
