In photovoltaic grid-connected (GC) and DG systems, one of the objectives that the grid-connected inverters (GCI) is the control of current coming from the photovoltaic modules or DG units. In this way, this paper describes a simple P/Q control strategy for three-phase GCI. Initially, the proposed control of the grid side is introduced.
To meet these requirements, a PQ control structure for the three-phase four-leg grid-connected inverter in a synchronous reference frame based on feedback linearization control ( FLC) is proposed.
This example simulation shows PSIM being used to control a grid link 3-phase inverter with real and reactive power control. Control in the dq reference frame is being implemented. The control scheme allows for real and reactive power to flow from the DC bus to the grid or from the grid to the DC bus.
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).
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
