      Agent based modeling of energy networks 

      González de Durana García, José María; Barambones Caramazana, Oscar; Kremers, Enrique; Varga, Liz (Elsevier, 2014-04-03)
      Attempts to model any present or future power grid face a huge challenge because a power grid is a complex system, with feedback and multi-agent behaviors, integrated by generation, distribution, storage and consumption ...

      Aspects to take into account in the application of mechanical calculation to high temperature low sag conductors 

      Albizu Flórez, Igor; Mazón Sainz-Maza, Angel Javier; Valverde Santiago, Víctor; Buigues Beraza, Garikoitz (The Institution of Engineering and Technology, 2010-05)
      Reconductoring with high temperature low sag (HTLS) conductors is an alternative to the traditional uprating methods. The obtained rating increase depends on the mechanical and thermal behaviour of the conductor. In this ...

      Flexible Strain-Tension Calculation Method for Gap-type Overhead Conductors 

      Albizu Flórez, Igor; Mazón Sainz-Maza, Angel Javier; Zamora Belver, Inmaculada (IEEE, 2009-07)
      Commercially available sag-tension programs give good results for most practical applications. However, they have some limitations concerning gap-type conductors. A separate aluminum and core creep calculation is needed ...

      Forecast Ratio and Security Analysis of Rating Forecasting Methods in an Overhead Line 

      Albizu Flórez, Igor; Fernández Herrero, Elvira; Mazón Sainz-Maza, Angel Javier; Alberdi, Rafael (The Institution of Engineering and Technology, 2017-01-26)
      The actual line rating in overhead lines varies with weather conditions. When a utility defines a rating value for the operation of the line, it takes into account both the security and the forecast ratio. The defined ...

      Influence of the conductor temperature error on the overhead line ampacity monitoring systems 

      Albizu Flórez, Igor; Fernández Herrero, Elvira; Mazón Sainz-Maza, Angel Javier; Bengoechea Aresti, Janire (The Institution of Engineering and Technology, 2011-04)
      Many real time overhead line ampacity monitoring systems are based on the calculation of the wind speed. The wind speed is obtained from the conductor temperature. The conductor temperature can be measured directly or it ...

      Multi-agent modelling for the simulation of a simple smart microgrid 

      Kremers, Enrique; González de Durana García, José María; Barambones Caramazana, Oscar (Elsevier, 2013-11)
      The smart grid is a highly complex system that is being formed from the traditional power grid, adding new and sophisticated communication and control devices. This will enable integrating new elements for distributed power ...

      Techniques for On-Line Diagnosis of Stator Shorted Turns in Induction Motors 

      Albizu Flórez, Igor; Zamora Belver, Inmaculada; Mazón Sainz-Maza, Angel Javier; Tapia Otaegui, María Aranzazu (Taylor & Francis, 2006-01)
      In low voltage induction motors, the first indication of a stator fault is the appearance of an inter-turn short circuit. For this reason, several attempts to diagnose reliably these short circuits have been made. Although ...

      Tension and Ampacity Monitoring System for Overhead Lines 

      Albizu Flórez, Igor; Fernández Herrero, Elvira; Eguía López, Pablo; Torres Iglesias, Esther; Mazón Sainz-Maza, Angel Javier (IEEE, 2013-01-01)
      Real time monitoring allows the determination of the line state and the calculation of the actual rating value. The real time monitoring systems measure sag, conductor tension, conductor temperature or weather related ...
