    • Design, control and testing of a modular multilevel converter with a single cell per arm in grid-forming and grid-following operations for scaled-down experimental platforms 

      Girona Badia, Jaume; Gomis Bellmunt, Oriol; Lledó Ponsati, Tomàs; Capó Lliteras, Macià; Cutululis, Nicolaos Antonio; Montesinos Miracle, Daniel; Heredero Peris, Daniel; Prieto Araujo, Eduardo (2022-03-01)
      Article
      Open Access
      Modular multilevel converters (MMC) can be used in several applications, especially (but not only) in high-voltage direct current (HVDC) and STATCOM. In order to develop experimental scaled-down test benches for lab ...

    • Development and implementation of a dynamic PV emulator with HMI interface for high power inverters 

      Heredero Peris, Daniel; Capó Lliteras, Macià; Miguel Espinar, Carlos; Lledó Ponsati, Tomàs; Montesinos Miracle, Daniel (2014)
      Conference lecture
      Open Access
      In this paper a 10 kVA photovoltaic emulator is presented. The system implemented generates photovoltaic V-I characteristic curves to analyse and test maximum power point tracking algorithms of real photovoltaic inverters ...
