4 FAQs about [Solar inverter pq control principle]

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 PQ inverter work?

An inverter in the PQ mode is effectively controlled as a current supply, only ever regulating the current exchanged with the grid. This current control loop operates in the direct-quadrature-zero (DQ0) frame, and employs over voltage and current limitations to simulate the protection of the switches (not depicted).

What is a control mode in a solar inverter?

The mode takes as input the active power (P, Watts) and the reactive power (Q, VAr) as set points. Most solar photovoltaic resources, and variable loads can be represented by this mode. An inverter in this control mode must be placed in a network with other "grid-forming" sources (e.g., swing, droop, or VSG) as it is "grid following".

What is a current controller in a photovoltaic inverter?

A current controller is employed to mitigate the harmonics in the current injected into the grid and regulate the power exchange between the plant and the grid. This paper presents a review of the current control strategies implemented for a single phase grid tied photovoltaic inverter.
