What is a multifunctional PV system?

Recently, PV systems, in addition to their primary role, the injection of green power into the grid, are used for current harmonics filtering and compensation of reactive power, hence the name multifunctional PV systems.

Is a quasi-two-stage multifunctional inverter suitable for photovoltaic (PV) applications?

Abstract: A novel quasi-two-stage multifunctional inverter (QMFI) for photovoltaic (PV) applications is proposed in this article. With the help of the quasi-two-stage architecture, part of active power can be directly transferred from PV arrays to the grid or load within a single power conversion stage and hence improve the efficiency.

Can multifunctional grid-connected photovoltaic systems improve power quality?

Potential solutions of power quality issues in modern power grid. The main aim of this work consists of proposing a new control strategy for multifunctional grid-connected photovoltaic systems (GCPVSs) to enhance the power quality at the point of common coupling (PCC) while considering the inverter-rated capacity.

Can solar photovoltaic power a three-phase multi-functional Unified Power Quality conditioner (MF-upqc)?

This paper demonstrates a three-phase multi-functional unified power quality conditioner (MF-UPQC) powered by solar photovoltaic (PV) using a voltage-controlled oscillator-less frequency-locked loop (VCO-less-FLL). The proposed system consists of an active shunt and series compensator linked with a shared DC link.

How to choose a multifunctional inverter?

The rated power of the multifunctional inverter must be considerably higher than the peak power of the PV array to ensure a significant increase in power quality under all environmental conditions. The trial-and-error approach used to select the type and number of the membership functions is time-consuming and labor-intensive.

Can multifunctional gcpvs improve power quality at PCC?

Conclusion In this paper, a new control strategy for multifunctional GCPVS to improve the power quality at the PCC was proposed. A two-stage grid-connected PV system employing a two-phase interleaved boost converter and a three-level neutral point clamped inverter was used to evaluate the control technique.
