2024, Renewable and Sustainable Energy Reviews Valeria Boscaino, Dario Di Cara Although the main function of the grid-connected inverter (GCI) in a PV system is to ensure an efficient DC-AC energy conversion, it must also allow other functions useful to limit the effects of the unpredictable and stochastic nature of the PV source.
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.
The control interaction issues in grid-connected inverters (GCI) can be mitigated at the unit level by modifying the converter control design, for instance, by improving the inner current control structure or upgrading the phase-locked loop (PLL). The PLL bandwidth and design are crucial in the control interaction between GCI and weak ac grid.
A number of problems must be solved simultaneously in the PV GCI control system, for instance, synchronization with the grid, satisfying the grid-connected voltage, tracking the grid-connected current and the attenuation of the harmonic distortions (Golzari et al., 2019, Hu et al., 2021, Liu et al., 2018, Sguarezi Filho and Ruppert Filho, 2012).
This aim is obtained by an accurate design of the GCI controller, which represents the most important part of the PV grid-connected system. In particular, the control strategies adopted can be categorized in the two main classifications: the DC side control and the grid side control.
The recommended requirements of an inverter on the PV side are to extract the Maximum Power Point (MPP) power (P mpp) from the PV module and to operate efficiently over the entire range of MPP of the PV module at varying temperatures and irradiation levels [37–39].
