  Real-Time Implementation of Two Grid-Forming Power Converter Controls to Emulate Synchronous Generators 

  Azuara-Grande, Luis Santiago; Gonzalez-Longatt, Francisco; Tricarico, Gioacchino; Wagle, Raju; Arnaltes, Santiago; Granizo, Ricardo (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-09)

  Modern power systems are experiencing unprecedented penetration of integrating renewable energy sources (RES) to tackle the so-called climate emergency. But the transition from synchronous generators to converter-interfaced generators also produces a few issues, some of them directly related to the reduction (or lack) of rotational inertia. The voltage source converters (VSCs) enabled with the ...

  Security Constrained Unit Commitment and Economic Dispatch by AC Sensitivity Factors 

  Tricarico, Gioacchino; Wagle, Raju; Azuara-Grande, Luis Santiago; Gonzalez-Longatt, Francisco; Dicorato, Maria; Forte, Giuseppe; Rueda, Jose Luis (Journal article; Tidsskriftartikkel, 2022-11-09)

  The dispatch schedule of the electrical power plant units is the result of the solution to the unit commitment optimisation problem, and it minimises the cost of production considering pre-defined technical limits. The security-constrained unit commitment problem has been defined as including the network constraints in the previously mentioned optimisation problem to obtain a feasible power system ...

  Zonal Day-Ahead Energy Market: A Modified Version of the IEEE 39-bus Test System 

  Tricarico, Gioacchino; Wagle, Raju; Dicorato, Maria; Forte, Giuseppe; Gonzalez-Longatt, Francisco; Torres, José Luis Rueda (Journal article; Tidsskriftartikkel, 2022-01-11)

  The increasing penetration of renewable energy resources (RES) in transmission system operating conditions require a suitable test system and a dataset to cope with current issues. RES penetration remarkably affects day-ahead market outcomes regarding zonal prices and dispatched generation levels. For this purpose, zonal day-ahead energy market models in the presence of RES in the generation mix ...

  Current Issues in Method and Practice Cross-community enactive research: a relational practice-based approach to academic engagement 

  Bertella, Giovanna (Journal article; Tidsskriftartikkel, 2023-03-13)

  To respond to the call for broader ways to understand academic engagement in sustainable tourism, I conceptualized a relational practice-based approach, termed cross-community enactive research. Relying on central ideas from the enactive research approach by entrepreneurship scholar Bengt Johannisson, which draws on autoethnography and action research, and the communities of practice theory by ...

  Evaluations of UAV-enabled FSO Communications in the Arctic 

  Pottoo, Sahil Nazir; Ellingsen, Pål Gunnar; Ho, Tu Dac (Journal article; Tidsskriftartikkel, 2022-02-16)

  This paper investigates the feasibility of using free space optics (FSO) for communication between multiple hovering unmanned aerial vehicles (UAVs) and a detection unit (DU) in the Arctic. The uniqueness that sets apart UAV-based FSO systems from conventional FSO systems is the dynamics of the system since location and inclination of the UAV changes over time due to wind load and UAV oscillations. ...
