Based on voltage feedforward solar inverter
Grid voltage feedforward control [18, 19, 20] can offset the influence of background harmonics of grid voltage on the grid-connected current, and it is widely used because it has the advantages of suppressing the inrush current during the startup of the grid-connected. . Grid voltage feedforward control [18, 19, 20] can offset the influence of background harmonics of grid voltage on the grid-connected current, and it is widely used because it has the advantages of suppressing the inrush current during the startup of the grid-connected. . In weak grid, feedforward of grid voltage control is widely used to effectively suppress grid-side current distortion of inverters caused by harmonics in point of common coupling (PCC) voltage. However, due to its introduction of a positive feedback loop related to the grid impedance, it results in. . e control loop feedforward terms on the stability of grid-forming inverters (GFMIs) connected to a grid. in IEEE J Emerg Select Top Power Electron 9:4236–4247, 2020; Lin et al. in IEEE Trans Power Electron. . Abstract: Grid-forming inverters, which are represented by droop control and virtual synchronous generator control, have been widely studied and applied because of their excellent grid-supporting ability and smooth off-grid switching. This paper proposes a novel current control technique with feed forward dc-voltage. .

LCL photovoltaic grid-connected inverter current inner loop control method
This paper proposes a simple current control scheme, based on the combination of deadbeat and PI control, for a three-phase voltage source inverter connected to the grid via an LCL filter. The LCL filter circuit parameters are analyzed, and a mathematical model of the three-phase grid-tied inverter in the dq rotating. . In this paper, an improved control method is proposed by introducing a compensation unit. The compensation unit can effectively compensate the system's phase around the crossover frequency, greatly enhancing the system's phase margin and stability. It is also capable of handling weak-grid. . Abstract-The utilization of inverters for the interconnection of distributed generators to the grid requires application of control systems capable of regulating the active and reactive output current, ensuring high power quality levels and achieving relative immunity to grid perturbations.
