      Text en actes de congrés
      Accés obert
      This paper reports a development of a statistical approach for fault detection and diagnosis in a PV system. Specifically, the overarching goal of this work is to early detect and identify faults on the DC side of a PV ...

    • Analysis of current and voltage indicators in grid connected PV (photovoltaic) systems working in faulty and partial shading conditions 

      Silvestre Bergés, Santiago; Kichou, Sofiane; Chouder, Aissa; Nofuentes Garrido, Gustavo; Karatepe, Engin (2015-06-12)
      Article
      Accés obert
      To ensure the optimization of the energy generated by grid connected PV (photovoltaic) systems is necessary to plan a strategy of automatic fault detection. The analysis of current and voltage indicators have demonstrated ...

    • Chapter 4: intelligent fault diagnosis of photovoltaic systems 

      Chouder, Aissa; Silvestre Bergés, Santiago (2022-07-13)
      Capítol de llibre
      Accés restringit per política de l'editorial
      Photovoltaic (PV) systems operating in real conditions of work are very often subject to several faults that may lower significantly the produced energy and shorten their availability. Therefore, powerful and trusted fault ...

    • Monitoring, modelling and simulation of PV systems using LabVIEW 

      Chouder, Aissa; Silvestre Bergés, Santiago; Taghezouit, Bilal; Karatepe, Engin (2013-05)
      Article
      Accés restringit per política de l'editorial
      This paper presents a detailed characterization of the performance and dynamic behaviour of photovoltaic systems by using LabVIEW real-time interface system. The developed software tool integrates several types of instruments ...

    • New procedure for fault detection in grid connected PV systems based on the evaluation of current and voltage indicators 

      Silvestre Bergés, Santiago; Aires da Silva, Mario; Chouder, Aissa; Guasch Murillo, Daniel; Karatepe, Engin (2014-05-27)
      Article
      Accés restringit per política de l'editorial
      In this work we present a new procedure for automatic fault detection in grid connected photovoltaic (PV) systems. This method is based on the evaluation of new current and voltage indicators. Thresholds for these indicators ...

    • Power adaptor device for domestic DC microgrids based on commercial MPPT inverters 

      Valderrama Blavi, H.; Bosque, J.M.; Guinjoan Gispert, Francisco; Marroyo, L.; Martínez Salamero, L. (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Article
      Accés restringit per política de l'editorial
      This paper presents a power adaptor device, referred to as smart panel device, allowing the connection of additional energy sources and storage elements to a domestic photovoltaic (PV) grid-connected system. The adaptor ...

    • Remote supervision and fault detection on OPC monitored PV systems 

      Silvestre Bergés, Santiago; Mora-López, Llanos; Kichou, Sofiane; Sanchez Pacheco, Francisco; Domínguez Pumar, Manuel (2016-09-01)
      Article
      Accés obert
      This paper presents a new approach for automatic supervision and remote fault detection of grid connected photovoltaic (PV) systems by means of OPC technology-based monitoring. The use of standard OPC for monitoring enables ...

    • State-space model of quasi-z-source inverter-PV systems for transient dynamics studies and network stability assessment 

      Monjo Mur, Lluís; Sainz Sapera, Luis; Mesas García, Juan José; Pedra Durán, Joaquim (2021-07-09)
      Article
      Accés obert
      Photovoltaic (PV) power systems are increasingly being used as renewable power generation sources. Quasi-Z-source inverters (qZSI) are a recent, high-potential technology that can be used to integrate PV power systems into ...
