Control of Power Converters in AC Microgrids
TL;DR: In this paper, a detailed analysis of the main operation modes and control structures for power converters belonging to micro-grids is carried out, focusing mainly on grid-forming, grid-feeding, and grid-supporting configurations.
Journal ArticleDOI
Multilevel Diode-Clamped Converter for Photovoltaic Generators With Independent Voltage Control of Each Solar Array
TL;DR: Simulation and experimental tests have been conducted with three PVAs connected to a four-level three-phase diode-clamped converter to verify the good performance of the proposed system configuration and control strategy.
Journal ArticleDOI
Grid Voltage Synchronization for Distributed Generation Systems Under Grid Fault Conditions
Alvaro Luna,Joan Rocabert,J. Ignacio Candela,Juan Ramon Hermoso,Remus Teodorescu,Frede Blaabjerg,Pedro Rodriguez +6 more
TL;DR: In this article, the synchronization capability of three advanced synchronization systems: the decoupled double synchronous reference frame phase-locked loop (PLL), the dual second order generalized integrator PLL, and the three-phase enhanced PLL are analyzed.
Journal ArticleDOI
Pulsewidth Modulations for the Comprehensive Capacitor Voltage Balance of $n$ -Level Three-Leg Diode-Clamped Converters
TL;DR: In this paper, the authors defined the virtual-space-vector (VV) concept for the three-level, three-leg neutral-point-clamped converter and provided the expressions of the leg duty-ratio waveforms corresponding to this family of PWMs for an easy implementation.
Journal ArticleDOI
Intelligent Connection Agent for Three-Phase Grid-Connected Microgrids
Joan Rocabert,Gustavo M. S. Azevedo,Alvaro Luna,Josep M. Guerrero,Jose Ignacio Candela,Pedro Rodriguez +5 more
TL;DR: In this article, the authors present a method oriented to carry out a stable intentional disconnection/reconnection of local grids from the main electrical network under grid-fault conditions.
