      Acosta Montalvo, Martha Nohemi; Andrade, Manuel A.; Vazquez, Ernesto; Sanchez, Francisco; Gonzalez-Longatt, Francisco; Rueda Torres, Jose Luis (Peer reviewed; Journal article, 2020)
      This paper presents a descriptive statistical analysis (DSA) of time-series of electro-mechanical quantities related to the frequency control (e.g. kinetic energy (KE), electrical frequency and power demand) of the Nordic ...
    • Improvement of the Frequency Response Indicators by Optimal UFLS Scheme Settings 

      Acosta Montalvo, Martha Nohemi; Andrade, Manuel A.; Vazquez, Ernesto; Adiyabazar, Choidorj; Gonzalez-Longatt, Francisco; Torres, Jose Luis Rueda; Palensky, Peter (Peer reviewed; Journal article, 2020)
      This research investigates the positive changes in the system frequency response indicators caused by the implementation of a set of optimal settings of an under-frequency load shedding (UFLS) scheme. The optimal under-frequency ...

      Gonzalez-Longatt, Francisco; Montalvo, Martha Nohemi; Andrade, Manuel A.; Vazquez, Ernesto; Chamorro, Harold R.; Sood, Vijay K. (Chapter, 2020)
      This paper presents a comparison of computational time required to build the admittance matrix of five test systems (ranging from 200 to 70,000 nodes) considering two formation approaches: element-by-element and matrix ...
    • Optimal Frequency Support of Variable-Speed Hydropower Plants at Telemark and Vestfold, Norway: Future Scenarios of Nordic Power System 

      Acosta Montalvo, Martha Nohemi; Pettersen, Daniel; Gonzalez-Longatt, Francisco; Peredo Argos, Jaime; Andrade, Manuel A. (Peer reviewed; Journal article, 2020)
      The integration of renewable resources is quickly growing in the Nordic power system (NPS), and it has led to increasing challenges for the operation and control of the NPS. Nordic countries require that the first-generation ...
    • Optimal under-frequency load shedding setting at Altai-Uliastai regional power system, Mongolia 

      Acosta Montalvo, Martha Nohemi; Adiyabazar, Choidorj; Gonzalez-Longatt, Francisco; Andrade, Manuel A.; Torres, José Rueda; Vazquez, Ernesto; Santos, Jesús Manuel Riquelme (Peer reviewed; Journal article, 2020)
      The Altai-Uliastai regional power system (AURPS) is a regional power system radially interconnected to the power system of Mongolia. The 110 kV interconnection is exceptionally long and susceptible to frequent trips because ...
