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).
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
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.
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.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
