    • Active and reactive power control of a PV generator for grid code compliance 

      Cabrera Tobar, Ana; Bullich Massagué, Eduard; Aragüés Peñalba, Mònica; Gomis Bellmunt, Oriol (2019-10-13)
      Article
      Open Access
      As new grid codes have been created to permit the integration of large scale photovoltaic power plants into the transmission system, the enhancement of the local control of the photovoltaic (PV) generators is necessary. ...

    • Capability curve analysis of photovoltaic generation systems 

      Cabrera Tobar, Ana; Bullich Massagué, Eduard; Aragüés Peñalba, Mònica; Gomis Bellmunt, Oriol (2016-12-15)
      Article
      Open Access
      The present article assesses the study of the PV generator capability curves for use in large scale photovoltaic power plants (LS-PVPPs). For this purpose, the article focuses on three main aspects: (i) the modelling of ...

    • Dynamic modelling and control of a PV generator for large scale applications 

      Cabrera Tobar, Ana; Aragüés Peñalba, Mònica; Gomis Bellmunt, Oriol (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report
      Restricted access - publisher's policy
      As large scale photovoltaic power plants are increasing their capacity, the new grid codes are requiring that these power plants have similar performance as conventional power plants do. Because of this, it is essential ...

    • Effect of variable solar irradiance on the reactive power response of photovoltaic Generators 

      Cabrera Tobar, Ana; Aragüés Peñalba, Mònica; Gomis Bellmunt, Oriol (2018)
      Conference report
      Restricted access - publisher's policy
      New grid requirements for large scale photovoltaic power plants (LS-PVPPs) demanding ancillary services make necessary the enhancement of photovoltaic (PV) generator's control. One of the challenges is the reactive power ...

    • Evaluation of a state observer for frequency estimation in a grid tied photovoltaic inverter 

      Cabrera Tobar, Ana; Gomis Bellmunt, Oriol; Carrasco, Juan A.; Barnes, Mike (2018)
      Conference report
      Restricted access - publisher's policy
      Ahstract-A phase locked loop (PLL) is commonly used to measure the electrical frequency deviations in PV grid tied inverters. However, this control is affected by sudden changes of power that usually happens with this type ...

    • Performance analysis of conventional PSS and fuzzy controller for damping power system oscillations 

      Banna, Hasan UI; Luna Alloza, Álvaro; Rodríguez Cortés, Pedro; Cabrera Tobar, Ana; Ghorbani, Hamidreza; Ying, Shaoqing (2014)
      Conference report
      Restricted access - publisher's policy
      Electro-mechanical oscillations are produced, in the machines of an interconnected power network, followed by a disturbance or due to high power transfer through weak tie lines. These oscillations should be damped as quickly ...

    • Performance of a small photovoltaic power plant under different meteorological conditions 

      Cabrera Tobar, Ana; Gomis Bellmunt, Oriol (2016)
      Conference report
      Restricted access - publisher's policy
      As the penetration of photovoltaic power plants (PVPP) increases, the impact on the reliability and stability of the bulk system is becoming significant. Thus, the present paper analyses the performance of a small PVPP ...

    • Topologies for large scale photovoltaic power plants 

      Cabrera Tobar, Ana; Bullich Massagué, Eduard; Aragüés Peñalba, Mònica; Gomis Bellmunt, Oriol (2016-06-01)
      Article
      Open Access
      © 2016 Elsevier Ltd. All rights reserved. The concern of increasing renewable energy penetration into the grid together with the reduction of prices of photovoltaic solar panels during the last decade have enabled the ...
