FAQS 4

What is a p/q control strategy for photovoltaic grid-connected inverters?

In photovoltaic grid-connected (GC) and DG systems, one of the objectives that the grid-connected inverters (GCI) is the control of current coming from the photovoltaic modules or DG units. In this way, this paper describes a simple P/Q control strategy for three-phase GCI. Initially, the proposed control of the grid side is introduced.

How does a grid connected inverter work?

The grid-connected inverter is transformed into a shunt-connected active filter at the point of common coupling through the process of separating the fundamental active load current component in order to provide a compensation signal. This action serves to improve the power quality of the utility grid 79.

What is a PQ control structure for a three-phase four-leg grid-connected inverter?

To meet these requirements, a PQ control structure for the three-phase four-leg grid-connected inverter in a synchronous reference frame based on feedback linearization control ( FLC) is proposed.

How to synchronize grid-connected inverters with grid current?

Initially, the proposed control of the grid side is introduced. Secondly, to synchronize the grid side voltage with grid current, a synchronous reference frame (SRF) based phase locked loop (PLL) is applied. Finally, the simulation of grid-connected inverters using PSIM is presented to illustrate concepts and results.
