On the stability criteria for inverter current control loops with LCL output filters and varying grid impedance
(IEEE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
The use of LC and LCL filters and grid impedance variations are creating new challenges on the controller design for current control loops of photovoltaic and wind turbine inverters. In the design process, stability criteria ...
DC capacitance reduction in three-phase photovoltaic inverters by using virtual impedance emulation
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
DC voltage regulation in grid-connected three-phase PV inverters is a fundamental requirement. In order to reduce the influence of the PV non-linear behavior and ensure stability in the whole operating range, the input ...
The generalized bode criterion: application to the dc voltage control of a three-phase photovoltaic grid-tied inverter
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
As renewable energies are becoming more important in the electrical generation system, power electronic converters are facing new design issues related not only to their components but also to their control loops. In this ...
Ramp-rate control in large PV plants: battery vs. short-term forecast
(2018)
info:eu-repo/semantics/conferenceObject,
The changeability in the power produced by utility-scale PV plants caused by shadows due to passing clouds can compromise grid stability. Traditionally, some kind of energy storage systems (ESS) is proposed as the solution ...
A comparative study of degradation and performance of thin film photovoltaic generators versus a multi-crystalline generator
(2013)
info:eu-repo/semantics/conferenceObject,
Thin film solar cells (TFSC) are supposed to have higher energy yield rates than crystalline silicon (Si-x) mainly possible by some enhancements like lower temperature coefficient and higher absorption of diffuse light. ...
Control strategy for an integrated photovoltaic-battery system
(IEEE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
In photovoltaic-battery systems, more attention is usually paid to the MPPT control while the battery management is put aside. This paper proposes two control strategies for an integrated PV-battery system, both of them ...
Evaluación de la aplicabilidad del año de referencia UNE-EN ISO 15927 ainstalaciones fotovoltaicas
(Fundación General de la Universidad Politécnica de Madrid, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
El desarrollo y expansión de las tecnologías de aprovechamiento de la energía solar hace necesario disponer de
datos meteorológicos representativos de un determinado lugar que permitan predecir el comportamiento
energético ...
