The dual closed-loop control structure for single-phase solar inverters typically consists of an outer voltage loop and an inner current loop. By establishing the mathematical model of the single-phase inverter, the current inner loop control can obtain rapid dynamic performance, and the voltage outer. . To address these limitations, this paper proposes an improved dual closed-loop control strategy that combines a modified linear active disturbance rejection controller (LADRC) for the voltage outer loop with a PI controller for the current inner loop. The inverter circuit is modeled, and simulation experiment and prototype verification are performed on Matlab.
[pdf] Summary: DC overcurrent in photovoltaic inverters is a critical issue affecting solar system performance. . Abstract—Grid-forming (GFM) inverters are increasingly rec-ognized as a solution to facilitate massive grid integration of inverter-based resources and enable 100% power-electronics-based power systems.
