TL;DR: Frequency-locked loops based on the linear Kalman filter, complex bandpass filter, and circular limit-cycle oscillator are considered, which have not been well analyzed in the literature, and limited knowledge about their real advantages/disadvantages compared to the SOGI-FLL exists.

TL;DR: In this article, the authors present a systematic methodology for the design and tuning of the current controller in LCL grid-connected converters for wind turbine applications, which is derived from the impedance/admittance stability formulation, which has been proved to be suitable for the controller design when the active damping is implemented and, on the other hand, has also been very suitable for system-level studies in applications with a high penetration of renewable energy resources.

TL;DR: In this article, a grid simulator based on a back-to-back inverter topology with resonant controllers is presented to test the performance of a given system under such distorted voltages.

TL;DR: This paper presents the integration of a commercial advanced metering infrastructure (AMI) in the context of a smart building with an energy management system (EMS), and power quality monitoring based on this AMI is explained.

TL;DR: This document analyses the large-signal stability for an inverter-based generator such as photovoltaic and wind power sources using the Popov method, which not only permits to generate a valid function but also to determine the stability region of the system.
