The grid-connected inverter must be controlled in such a way that not only it injects a current with low total harmonic distortion (THD), but also allows controlling the injected reactive power into the grid selecting a proper power factor according to the grid demands: active or reactive power.
As aforementioned, the inverter is interconnected to the grid, so it should fulfill the grid standards as well. These standards includes power quality, grid ride through capability and islanding prevention . Power quality is mainly measured on the basis of Power Factor (PF) and Total Harmonic Distortion (THD).
The characteristics of different communication methods of inverters are obvious, and the application scenarios are different. In order to better weave the underlying network of energy digitization and intelligent development, choose the most appropriate communication method according to local conditions.
Parameters of the grid-connected inverter system. The simulations of the steady-state operations are carried out when the MPC method is used. The given active power is 1000 W, and the given reactive power is 0 Var. The grid-connected currents are shown in Fig. 13.7A, and the spectrogram of the currents is shown in Fig. 13.7B.
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.
There are typically three possible inverter scenarios for a PV grid system: single central inverter, multiple string inverters and AC modules. The choice is given mainly by the power of the system. Therefore, AC module is chosen for low power of the system (around 100 W typical).
