6 FAQs about [Photovoltaic power plant inverter interface]

What is a PV inverter?

As clearly pointed out, the PV inverter stands for the most critical part of the entire PV system. Research efforts are now concerned with the enhancement of inverter life span and reliability. Improving the power efficiency target is already an open research topic, as well as power quality.

Can grid-connected PV inverters improve utility grid stability?

Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.

What are the different types of PV inverters?

There are four configurations commercially accepted [26 – 30]. Central-plant inverter: usually a large inverter is used to convert DC output power of the PV array to AC power. In this system, the PV modules are serially string and several strings are connected in parallel to a single dc-bus. A single or a dual-stage inverter can be employed.

What is a central inverter?

The main configuration of central inverters is designed to interface large PV power plants to the utility grid.

Why are transformerless inverters used in grid-connected PV systems?

Transformerless inverters gained more attention in grid-connected PV systems due to demands of power density, high efficiency, reliability, and low cost. However, leakage current is produced through the stray capacitances between the PV array and the ground. It is generated due to the fluctuation of common-mode voltages between PV neutral and grid.

What are PV inverter topologies?

PV inverter topologies have been extensively described throughout Section 3 with their peculiarities, characteristics, merits and shortcomings. Low-complexity, low-cost, high efficiency, high reliability are main and often competing requirements to deal with when choosing an inverter topology for PV applications.
