Contact UsIn interactive PV grid topologies, it is common to pair a PV inverter with an SAPF (active power filter) and a voltage and reactive control superstation in order to prevent the costs of the power circuit from rising too high.
The purpose of this research is to evaluate advanced APFs for reducing power switches and grid-connected weight, cost, and scale. Several studied APF inverter topologies, including single-phase, three-phase AC–AC, back-to-back, and common parameters, have been considered.
Abstract: Grid-connected photovoltaic (PV) systems have become a significant area of interest for research scientists. Given this, this article presents a nonlinear control of grid-connected PV systems using active power filter (APF) with three-phase three-level neutral point clamped (NPC) inverter.
This connects the power grids to transformer-free, multilevel, multiple-function inverters that are centralized on the APF when used in PV and WECS. Grid-connected PV inverters without transformers are a great way to lower grid-connected system costs while also reducing the size and weight of the grid-connected system.
The PV inverter converts the electricity produced by the solar photovoltaic device into usable electricity, while also filtering the harmonics of the load current [47, 48, 49]. Integrating an APF into the grid-connected PV system enhances its performance, reliability, and reduces current harmonic distortions [50, 51, 52, 53, 54, 55, 56].
