4 FAQs about Three-phase grid-connected inverter control

Can a three-phase grid-connected inverter be controlled under unbalanced grid situations?

Presented in this paper is a method of bidirectional real and reactive power control of a three-phase grid-connected inverter under unbalanced grid situations. Unbalanced three-phase load and unbalanced grid impedance are illustrations of unbalanced grid issues that have been investigated.

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 are grid-connected inverters?

With the rapid development of distributed generation technologies, a large number of renewable energy sources, such as wind power, photovoltaic power and energy storage, are connected to the grids through power electronic devices, among which grid-connected inverters are the core components [1, 2].

Can a PI-controller control a grid-connected three-phase inverter?

However, reference improved and simplified this approach by using just one PLL, and power control can also be accomplished with a PI-controller. Using a proportional resonance (PR)-controller, power control of grid-connected three-phase inverters under unbalanced grid situations has been explored in [7, 8].
