Grid-Following and Grid-Forming Converter Control Comparison Under Fault Conditions
2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia), 2021Traditionally 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), 2021This 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)

Observer-Based Single-Sensor Control Schemes for LCL-Filtered Grid-Following Inverters
IEEE transactions on industrial electronics (1982. Print), 2023In the single-sensor grid-following control of LCL-type grid-connected inverters, extended observers, which behave as “virtual sensors,” are typically employed for active damping, disturbance rejection, current tracking, and grid synchronization. However,
