An Alternate Representation of the Vector of Apparent Power and Unbalanced Power in Three-Phase Electrical Systems

Blasco Espinosa, Pedro Angel; Montoya-Mira, Rafael; Diez-Aznar, José-Manuel; Montoya Villena, Rafael (MDPI AG, 2020-06)

[EN] Low-voltage distribution systems are typically unbalanced. These ine¿ciencies cause unbalanced powers that can significantly increase the apparent power of the system. Analysing and measuring these ine¿cient powers ...
Effects of the Selected Point of Voltage Reference on the Apparent Power Measurement in Three-Phase Star Systems

León-Martínez, Vicente; Montañana-Romeu, Joaquín; Peñalvo-López, Elisa; Álvarez, Carlos (MDPI AG, 2020-02)

[EN] The phenomenon responsible for the different apparent powers measured in a subsystem of a three-phase star-configured system, based on the voltage reference point, was identified in this paper using specific components ...
Formulations for the apparent and unbalanced power vectors in three-phase sinusoidal systems

León-Martínez, Vicente; Montañana-Romeu, Joaquín (Elsevier, 2018)

[EN] Buchholz's apparent power and its derived unbalanced power, determined from the quadratic difference between the apparent power and the positive-sequence apparent power, are formulated in this paper in vector notation ...
Novel Conceptual Architecture for the Next-Generation Electricity Markets to Enhance a Large Penetration of Renewable Energy

Rodríguez-García, Javier; Ribó-Pérez, David Gabriel; Álvarez, Carlos; Peñalvo-López, Elisa (MDPI AG, 2019-07-01)

[EN] A transition to a sustainable energy system is essential. In this context, smart grids represent the future of power systems for efficiently integrating renewable energy sources and active consumer participation. ...
Sistemas Integrados de Potencia en Buques Offshore: Control, tendencias y retos

Valera García, Juan José; Atutxa Lekue, Íñigo (Elsevier, 2016-01-10)

[EN] The offshore vessels require a high precision speed control and dynamic positioning. Adverse weather conditions and/or rough waves give rise to high disturbances that must be rejected by the control system to keep the ...
