6 FAQs about [Photovoltaic inverter control strategy]

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 a control strategy for a three-phase PV inverter?

Control strategy A control strategy is proposed for a three-phase PV inverter capable of injecting partially unbalanced currents into the electrical grid. This strategy aims to mitigate preexisting current imbalances in this grid while forwarding the active power from photovoltaic panels.

How do inverters affect a grid-connected PV system?
