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).
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.
The test system is described shown in Fig. 13.6, the grid-connected inverter system is simulated using Matlab/Simulink. The simulation model mainly includes the main circuit module and the control module of a three-phase two-level inverter. The grid-connected inverter can distribute the active and reactive power according to the control.
The grid-connected inverter can distribute the active and reactive power according to the control. Therefore, the control objectives are designed as tracking active power and reactive power. The parameters of devices and circuits are shown in Table 13.1.
In the grid-connected inverter, the associated well-known variations can be classified in the unknown changing loads, distribution network uncertainties, and variations on the demanded reactive and active powers of the connected grid.
