6 FAQs about [Interpretation of photovoltaic inverter curve]

What are the parameters of a PV inverter?

It is necessary to mention that the highest temperature limits the output active power that the PV generator can supply to the system. The dc voltage and the modulation index are also parameters that a ects to the PQ capability curve and the operation of the PV inverter.

What are the parameters of PV inverter PQ curve?

From the mathematical analysis and the simulation some conclusions are discussed. The PQ capability curves of the PV inverter are characterized by four main parameters: solar irradiance, temperature, dc voltage and the modulation index. These values are dependent on each other in order to obtain the complete PQ curve.

Are PV generator capability curves suitable for large scale photovoltaic power plants?

The operational limits of the PV array and the inverter are analysed. The complete capability curve of the PV generator is studied in detail. The present article assesses the study of the PV generator capability curves for use in large scale photovoltaic power plants (LS-PVPPs).

What is a PV characteristic curve?

Figure 1. Classification of photovoltaic technologies [18, 19, 20, 21]. The PV characteristic curve, which is widely known as the I–V curve, is the representation of the electrical behavior describing a solar cell, PV module, PV panel, or an array under different ambient conditions, which are usually provided in a typical manufacturer’s datasheet.

How do you determine the SOA of a PV inverter?

The solar irradiance and the temperature are important parameters to identify the SOA of the PV inverter. First, the highest solar irradiance and the lowest temperature determine the highest active power that the PV inverter can supply to the grid.

How does a PV inverter work?

The PV inverter under analysis is a VSC converter that exchanges power from the PV array (DC side) to the grid (AC side). This inverter has two IGBT per branch and one inductor per line as a filter. Furthermore, the transformer is modelled as an inductor. In this case, the filter and the transformer inductance are represented by (L f).
