    • Knowing power grids and understanding complexity science 

      Rosas Casals, Martí; Bologna, Sandro; Bompard, Ettore; D'Agostino, Gregorio; Ellens, Wendy; Pagani, Giuliano A.; Scala, Antonio; Verma, Trivik (InderScience Publishers, 2015-02-02)
      Article
      Open Access
      Complex networks theory has been well established as a useful framework for studying and analysing structure, dynamics and evolution of many complex systems. Infrastructural and man-made systems like power grids, gas and ...
    • Local frequency restoration for droop-controlled parallel inverters in islanded microgrids 

      Rey López, Juan Manuel; Rosero Chandi, Carlos Xavier; Velasco García, Manel; Martí Colom, Pau; Miret Tomàs, Jaume; Castilla Fernández, Miguel (2018-01-01)
      Article
      Open Access
      In islanded microgrids, voltage source inverters working in parallel are expected to provide regulation of the local frequency while granting active power sharing. This paper presents a local control approach at each ...

      Other
      Open Access
      Through the history of Electrical Engineering education, vectorial and phasorial diagrams have been used as a fundamental learning tool. At present, computational power has replaced them by long data lists, the result of ...
    • Network hierarchy evolution and system vulnerability in power grids 

      Luo, Lingen; Han, Bei; Rosas Casals, Martí (2016-12-01)
      Article

      The seldom addressed network hierarchy property and its relationship with vulnerability analysis for power transmission grids from a complex-systems point of view are given in this paper. We analyze and compare the evolution ...
    • On the difficulty (and success) of correlating empirical data and (extended) topological measures in power grid networks 

      Luo, Lingen; Bompard, Ettore; Rosas Casals, Martí (2012)
      Conference report
      Restricted access - author's decision
      Power grids have entered the complex networks realm for quite a long time now. Their structure (i.e., topology) and dynamics have been thoroughly studied and many topological measures have been used in order to classify ...
