    • Control Optimization of the Offshore HVDC Grid based on Modular Multilevel Converter for Improving DC Voltage Stability 

      Elahidoost, Atousa; Tedeschi, Elisabetta (Peer reviewed; Journal article, 2020)
      The aim of this paper is to reduce the voltage oscillation of the HVDC cable in an offshore point-to-point configuration based on the modular multilevel converter. An optimization methodology based on semidefinite programming ...

    • Harmonic Resonance Mode Analysis in dq Domain 

      Taffese, Abel Assegid; Tedeschi, Elisabetta (Journal article, 2017)
      Harmonic Resonance Mode Analysis (HRMA) is a technique developed to study harmonic resonance in a power system. Compared to conventional resonance analysis techniques, HRMA is a powerful method that can indicate the origin ...

    • Marine Current Turbines and Generator preference. A technology review 

      Røkke, Astrid; Nilssen, Robert (Journal article; Peer reviewed, 2013)
      Marine current power is a significant energy resource yet to be exploited for electricity production. Several novel turbine technologies can be found on the market, and new ones emerge every year. This study found that the ...

    • Nonlinear Control Structure of Grid Connected Modular Multilevel Converters 

      Hajizadeh, A.; Norum, Lars Einar; Ahadpour Shal, A (Journal article; Peer reviewed, 2017)
      This paper implements nonlinear control structure based on Adaptive Fuzzy Sliding Mode (AFSM) Current Control and Unscented Kalman Filter (UKF) to estimate the capacitor voltages from the measurement of arm currents of ...

    • Optimal Compensation of Harmonic Propagation in a Multi-Bus Microgrid 

      Skjong, Espen; Suul, Jon Are Wold; Molinas Cabrera, Maria Marta; Johansen, Tor Arne (Journal article; Peer reviewed, 2016-05)
      This paper discusses how an Active Power Filter (APF) can be utilized for system-wide harmonic mitigation in a microgrid with multiple sources of harmonic distortion located at different buses. A two-bus microgrid system ...
