Grid-Following and Grid-Forming Converter Control Comparison Under Fault Conditions

2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia), 2021
Traditionally control of grid-connected converters is based on a grid-following structure, where a Phase Locked Loop is responsible for tracking the angle of the AC grid. However, such control structure leads to stability problems for weak and low inertia grids. Then, a grid-forming control structure is presented as a potential solution.

Modeling and Control of Grid-following Single-Phase Voltage-Sourced Converter

2020 52nd North American Power Symposium (NAPS), 2021
This paper presents modeling and control of a grid-following single-phase voltage-sourced converter (VSC). The electromagnetic transient (EMT) simulation is carried out via MATLAB/Simulink with SimPowerSystems Toolbox. Detailed IGBT switches are included in the DC/AC inverter model. Second-order generalized integrator-based Phase-Locked-Loop (SOGI-PLL)

PLL-less Active and Reactive Power Controller for Grid-Following Inverter

2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020
This paper presents a control scheme for single-phase grid-following inverters that does not rely on the phase-locked-loop (PLL) algorithm for synchronizing the injected current with the grid. The absence of the PLL avoids unstable low damping modes that are possibly originated from the PLL’s nonlinear nature.
