Comparison of linear and and small-signal models for inverter-based microgrids
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
Frequency and voltage regulation in droop-based microgrids is generally modeled using small-signal analysis. In order to ensure accuracy, existing models do not decouple real and reactive power responses. However, the ...
State-of-charge-based droop control for stand-alone AC supply systems with distributed energy storage
(Elsevier, 2015)
Artículo / Artikulua,
The droop method is an advantageous technique for stand-alone AC supply systems, allowing for power sharing among various inverters with no need for communication cables. However, in stand-alone systems with multiple ...
High frequency power transformers with foil windings: maximum interleaving and optimal design
(IEEE, 2015)
Artículo / Artikulua,
Foil conductors and primary and secondary interleaving are normally used to minimize winding losses in high frequency transformers used for high-current power applications. However, winding interleaving complicates the ...
A comprehensive model for lithium-ion batteries: from the physical principles to an electrical model
(Elsevier, 2018)
Artículo / Artikulua,
The growing interest in e-mobility and the increasing installation of renewable energy-based systems are leading to rapid improvements in lithium-ion batteries. In this context, battery manufacturers and engineers require ...
Frequency-based energy management strategy for stand-alone systems with distributed battery storage
(IEEE, 2015)
Artículo / Artikulua,
Distributed generation is an attractive solution for stand-alone AC supply systems. In such systems, the installation of two or more energy-storage units is recommended for system redundancy and may also be required when ...
Energy management strategy for a battery-diesel stand-alone system with distributed PV generation based on grid frequency modulation
(Elsevier, 2014)
Artículo / Artikulua,
A hybrid PV-Battery-Diesel configuration is very attractive for stand-alone systems in terms of cost and reliability. In many applications, the battery and the diesel generator are centralized and generate the AC grid while ...
Control of a single-switch two-input buck converter for MPPT of two PV strings
(IEEE, 2015)
Artículo / Artikulua,
In this paper, the Two-Input Buck (TIBuck) converter is proposed as the DC/DC stage for photovoltaic (PV) cascaded converters. This converter is attractive for this application because it is cost-effective and reliable and ...
Parameter-independent control for battery chargers based on virtual impedance emulation
(IEEE, 2018)
Artículo / Artikulua,
An effective battery voltage regulation is fundamental to extend battery lifetime and to avoid overvoltage. However, the design of this regulation is complicated due to the wide battery impedance range, which, when dealing ...
Modeling of small wind turbines based on PMSG with diode bridge for sensorless maximum power tracking
(Elsevier, 2013)
Artículo / Artikulua,
The Permanent Magnet Synchronous Generator (PMSG) with diode bridge is frequently used in small Wind Energy Conversion Systems (WECS). This configuration is robust and cheap, and therefore suitable for small WECS. In order ...
