Based on dual-loop control of three-phase inverter

4 FAQs about [Based on dual-loop control of three-phase inverter]

How is a three-phase PV Grid-connected inverter designed?

The three-phase PV grid-connected inverter was designed based on the LQR method, where the tracking error was adjusted to zero through integration (Al-Abri et al., 2024). The disturbance rejection ability of the PV GCI was improved by designing the linear state inaccuracy feedback control policy (Zhou et al., 2021).

What is a grid-connected inverter?

As the core device of the new energy production system, the grid-connected inverter plays a crucial role in transforming new energy into electrical energy. Rega

What is a current loop optimal controller?

Therefore, the proposed current loop optimal controller, based on the off-policy IRL method, effectively controls the voltage and current of the grid connection in the semi-physical simulation experiment. It minimizes the THD of the grid connection, satisfying the requirements for grid connection. Fig. 11.

What is voltage-current dual-loop control (VDC)?

Firstly, the voltage-current dual-loop control (VDC) structure is adopted, where the model of the current loop is restructured benefitting from the current tracking principle.
