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 ... -
Framework for Real-Time Simulation of Hardware in the Loop Applied to Primary Frequency Control
Barrios-Gomez, J.A.; Sanchez, Francisco; Gianfranco, Claudio; Gonzalez-Longatt, Francisco; Acosta Montalvo, Martha Nohemi; Denysiuk, Serhii; Strelkova, Halyna (Chapter, 2020)This research paper proposes a framework to perform (hardware in the loop) HIL simulation in real-time (RT), the framework includes steps for the formulation of the Target RT Computer and Open Source System, which are ... -
Frequency Support of Fast-Multi-Energy Storage Systems in Low Rotational Inertia Scenarios
Ersdal, Anne Mai; Acosta Montalvo, Martha Nohemi; Gonzalez-Longatt, Francisco; Rueda Torres, Jose Luis; Palensky, Peter (Chapter, 2020)Modern power systems are increasing the connection of power electronic converters (PECs), and new inertia-less technologies displace the synchronous generation units. Therefore, the total rotational system inertia is ... -
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 ... -
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 ... -
