6 FAQs about [Power transmission sequence of Kono photovoltaic inverter]

Can a PV inverter integrate with the current power grid?

By using a reliable method, a cost-effective system has to be developed to integrate PV systems with the present power grid . Using next-generation semiconductor devices made of silicon carbide (SiC), efficiencies for PV inverters of over 99% are reported .

Why does PV inverter output voltage contain high order harmonics?

According to the previous analysis, the increase of the PV inverter output power may cause PV output voltage to contain high order harmonics under the weak grid, which are mainly distributed near the resonance peak of output filter LCL of PV inverter.

Does a grid-connected photovoltaic inverter system have a harmonic governance ability?

Based on the above analysis, it can be concluded that the harmonic amplification coefficients of the whole grid-connected system in the whole frequency band are all around 1 when the grid contains background harmonics, indicating that the grid-connected photovoltaic inverter system has no harmonic governance ability.

How does a power converter work in a grid-connected PV system?

Fig. 2 shows the block diagram of the grid-connected PV system where a DC–DC converter is responsible for operating at maximum power point (MPP) by embedding an appropriate MPPT algorithm in the MPPT controller. By using a power converter, the PV system is pivoted to the grid.

How a PV Grid connected inverter generates output harmonics?

The output harmonics of the PV grid-connected inverter are generated under the action of grid voltage harmonics, resulting in corresponding harmonics of its output current. The fundamental reason is that the output harmonics of the inverter are generated by the excitation of harmonic voltage source.

How does a PV power conversion system work?

In large utility-scale PV power conversion systems, central inverters are utilised ranging from a few hundreds of kilowatts to a few megawatts. In the generator junction box, PV strings are connected in P by using string diodes, isolators, and fuses to block reverse current and to isolate strings when needed.
