Feedforward

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. .
