6 FAQs about [Photovoltaic inverter voltage control algorithm]

How do PV inverters control stability?

The control performance and stability of inverters severely affect the PV system, and lots of works have explored how to analyze and improve PV inverters’ control stability . In general, PV inverters’ control can be typically divided into constant power control, constant voltage and frequency control, droop control, etc. .

What is a photovoltaic inverter control strategy?

The main objective of the inverter control strategy remains to inject the energy from the photovoltaic panels into the electrical grid. However, it is designed to inject this power through unbalanced currents so that the local unbalance introduced by the inverter contributes to the overall rebalancing of the grid’s total currents.

What is the control performance of PV inverters?

The control performance of PV inverters determines the system’s stability and reliability. Conventional control is the foundation for intelligent optimization of grid-connected PV systems. Therefore, a brief overview of these typical controls should be given to lay the theoretical foundation of further contents.

What is constant power control in a PV inverter?

In general, PV inverters’ control can be typically divided into constant power control, constant voltage and frequency control, droop control, etc. . Of these, constant power control is primarily utilized in grid-connected inverters to control the active and reactive power generated by the PV system .

Can PV inverters be controlled in voltage control mode?

However, when the main grid is cut off from the PV system, standalone operation must be achieved while operating in voltage control mode. This brings new challenges for the control of PV inverters, i.e., voltage regulation and harmonic elimination.

How do PV inverters control a low-voltage network?

Thus, a control method for PV inverters is presented, so that they inject unbalanced currents into the electrical grid with the aim of partially compensating any current imbalances in the low-voltage network where inverters are connected, but in a decentralized way.
