    • A simple rule-based energy management system for off-grid systems 

      Sigrist, Lukas; Rouco Rodríguez, Luis; Saboya Bautista, Inmaculada; Díez Maroto, Luis
      Off-grid systems are systems that are not interconnected with the grid and that congruently operate in islanded mode permanently. In order to operate the off-grid system efficiently, an energy management system (EMS) is ...

    • Development perspectives of Power to Gas (P2G) in Spain 

      Saboya Bautista, Inmaculada; Rouco Rodríguez, Luis; Linares Llamas, Pedro; Cortés Muñoz, Paloma; Ferragut Ferretjans, Francisco; Martínez Gonzalo, Maria Piedad; García Martínez, Fernando; Chamberlain, John
      Wind generation curtailments can occur in power systems as wind penetration increases. An alternative to curtailments is Power to Gas (P2G). The fundamental idea of P2G is to use the surplus energy, that cannot be incorporated ...

    • Impact of high-speed trains in small isolated power systems phase to phase unbalances 

      Saboya Bautista, Inmaculada; Egido Cortés, Ignacio; Pilo De La Fuente, Eduardo; Rouco Rodríguez, Luis (Sin editorial (New Forest, Reino Unido), 2012-09-11)
      High-speed trains are more and more widely used around the world. They are commonly installed in interconnected power systems by connecting each traction substation directly in different nodes among the network. The ...

    • Machine learning based algorithms to dispatch multiple rapid-start units in AGC of power systems 

      Saboya Bautista, Inmaculada; Lobato Miguélez, Enrique; Egido Cortés, Ignacio; Sigrist, Lukas (2020-02-01)
      This paper proposes a set of different alternatives of machine learning based algorithms (MLBA) - based on decision trees, neural networks and clustering techniques - to start up multiple rapid start units in AGC operation ...

    • Modelling of a thermo-electric energy management system including heat pumps for an off-grid system 

      Sigrist, Lukas; Fernández de Bobadilla, Jose María; Lobato Miguélez, Enrique; Rouco Rodríguez, Luis; Saboya Bautista, Inmaculada; Díez Maroto, Luis (2019-04-01)
      This paper presents a thermo-electric model to implement the energy management system (EMS) of an off-grid system. The EMS is formulated as a unit commitment problem where thermal and electrical components are dispatched ...

    • MOPSO-tuning of a threshold-based algorithm to start up and shut-down rapid-start units in AGC 

      Saboya Bautista, Inmaculada; Egido Cortés, Ignacio; Lobato Miguélez, Enrique; Sigrist, Lukas (2019-06-01)
      Units within a frequency control area, participating in the automatic generation control (AGC) are usually spinning generating units already connected to the network and operating outside their range of optimal performance. ...

    • Operation of rapid start units in an AGC area 

      Egido Cortés, Ignacio; Fernández Bernal, Fidel; Rouco Rodríguez, Luis; Saboya Bautista, Inmaculada (2012-01-01)
      Rapid Start units can be used in an AGC area as units that can participate in AGC regulation but that remain offline until they are needed. The generation cost of these units is high so usually it is preferred to keep them ...

    • Performance evaluation of start-up decisions of rapid-start units for AGC 

      Saboya Bautista, Inmaculada; Egido Cortés, Ignacio; Lobato Miguélez, Enrique (2015-11-01)
      Generating units, participating in the secondary frequency control of a control area, are usually spinning units already connected to the network and operating outside their range of optimal performance. This paper deals ...

    • Start-up decision of a rapid-start unit for AGC based on machine learning 

      Saboya Bautista, Inmaculada; Egido Cortés, Ignacio; Rouco Rodríguez, Luis (2013-11-01)
      Units within a control area, participating in the secondary frequency control, are usually spinning generating units already connected to the network and operating outside their range of optimal performance. This paper ...
