6 FAQs about [The core competitiveness of photovoltaic inverters]

Can PV inverters be used for local reactive power compensation?

With the increasing adoption of photovoltaic systems (PVs) in distribution grid, many researchers and grid operators have proposed and started to utilise PV inverters for local reactive power compensation (RPC). The local RPC has been shown to reduce losses in the system, and to help maintain voltage within acceptable range.

What is the performance of PV inverters?

The performance of PV inverters mainly relies on power electronic devices. Nowadays, silicon (Si)-based devices, including Si insulated-gate bipolar transistor (IGBT) and Si diode, are commonly used in inverters. However, over the past four decades, the performance of Si devices has reached its boundary .

How does a PV inverter affect RPC?

Nevertheless, the RPC using a PV inverter increases the current flowing through it, and hence the losses and the temperature of its components. As a result, the lifetime of the inverter will be reduced with increasing reactive power usage, incurring costs to the system owner and increases the PV levelised cost of electricity (LCOE).

What are the challenges of SiC-based PV inverter?

However, the SiC-based PV inverter is challenged by many issues, as shown in Fig. 12. Due to the very fast switching speed, high dv / dt, and di / dt, the employed SiC devices cause serious ringing, cross-talk, etc. These issues are discussed in detail as follows. Fig. 12. Configuration of SiC-based PV inverter with challenges. 4.1.

What is the peak efficiency of a PV inverter?

The usual peak efficiency is 94–98%. The power loss of a PV inverter is mainly caused by the switching and conduction loss of Si devices. To further increase the efficiency of PV inverters, the performance of Si devices is limited, and the emerging SiC devices with less loss should be employed. Fig. 1.

How much power can a Si based PV inverter produce?

Nowadays, for commonly used Si-based PV inverter, the rated power capacity ranges from several watts to hundreds of kilowatts. The typical topologies can be classified into three categories, namely, low-frequency isolated, high-frequency isolated, and non-isolated.
