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 ...
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 ...
Comparison of State-of-Charge estimation methods for stationary Lithium-ion batteries
(IEEE, 2016)
Contribución a congreso / Biltzarrerako ekarpena,
An accurate monitoring of the State of Charge (SoC) is mandatory for an efficient management of a Lithium-ion battery. Batteries of stationary systems barely have long resting periods when the cumulative errors can be ...
