Novel Active Damping Design Based on a Biquad Filter for an LLCL Grid-Tied Inverter
Energies, 2023 LLCL filters for grid-tied inverters have been adopted to get better performance for the harmonics near the switching frequency than commonly used LCL filters. However, the resonant peak caused by a pair of unstable resonance poles of the LLCL filters is

Voltage Weak DC Distribution Grids [PDF]
Electric Power Components and Systems, 2017 AbstractThis paper describes the behavior of voltage weak DC distribution systems. These systems have relatively small system capacitance. The size of system capacitance, which stores energy, has a considerable effect on the value of fault currents, control complexity, and system reliability.

Active Damping Adaptive Controller for Grid-Connected Inverter Under Weak Grid [PDF]
IEEE Access, 2021 The stability of grid-connected inverters is very sensitive to varying grid impedance, especially in the weak grid condition. In this paper, based on the Lyapunov method and with the micro-grid impedance identification, an active damping adaptive control strategy is proposed to guarantee local asymptotic stability for an LCL inverter system.

An improving control strategy for grid -connected current in weak grid [PDF]
E3S Web of Conferences, 2021 The traditional proportional feedforward control strategy can suppress the low order harmonics in the strong power grid, but in the weak power grid environment, the grid impedance will have an adverse impact on the stability of the system, resulting in the proportional feedforward control can not suppress the low order harmonics well. In order to solve
