All-pass-filter-based active damping for VSCs with LCL filters connected to weak grids [PDF]
, 2018 LCL filters are commonly used to connect Voltage Sourced Converters (VSCs) to the grid. This type of filter is cheaper than a single inductor for the same current THD, but it generates resonance problems if no active or passive damping method is applied.

Single-Sensor Control of LCL-Filtered Grid-Connected Inverters [PDF]
IEEE Access, 2019 Owing to the filter resonance and background harmonics, the current control for the LCL-filtered grid-connected inverter should be carefully designed to ensure stable operation. Prior-art current control methods normally require extra sensors to achieve the damping of the resonance, or sophisticated active damping should be employed.
