6 FAQs about [Photovoltaic inverter power generation sequence]

Are three-phase smart inverters suitable for grid-connected photovoltaic system?

The main purpose of this paper is to conduct design and implementation on three-phase smart inverters of the grid-connected photovoltaic system, which contains maximum power point tracking (MPPT) and smart inverter with real power and reactive power regulation for the photovoltaic module arrays (PVMA).

How does a PV inverter work?

Hence, the inverter is used to inject reactive power in an appropriate amount. The grid code prescribes this amount, based on as to how severe is the dip in the grid voltage. As the power system operators require injection of reactive power from PVs during period of low-voltage-ride-through.

Can a PV inverter be used as a reactive power generator?

Using the inverter as a reactive power generator by operating it as a volt-ampere reactive (VAR) compensator is a potential way of solving the above issue of voltage sag . The rapid increase in using PV inverters can be used to regulate the grid voltage and it will reduce the extra cost of installing capacitor banks.

How to provide voltage support in PV inverter?

To provide voltage support at the PCC, reactive power is injected into the grid under fault conditions as per the specified grid codes. As previously discussed, the simultaneous injection of peak active power from PVs and reactive power into the grid for voltage support can trigger the over current protection mechanism in PV inverter.

What are the different types of PV generators?

There are two typical configurations of PV generator in power system applications, namely, single-stage and two-stage as shown in Fig. 1a, Fig. 1b. A single-stage PV generator uses only one converter to complete both the maximum power point tracking (MPPT) and the power grid connection.

How do inverters affect a grid-connected PV system?

For a grid-connected PV system, inverters are the crucial part required to convert dc power from solar arrays to ac power transported into the power grid. The control performance and stability of inverters severely affect the PV system, and lots of works have explored how to analyze and improve PV inverters’ control stability .
