The measured phase angle of the utility grid voltage is important information for a grid-tied system used to set inverter reference control signal (Panda et al., 2016). In a grid-tied PV system, the grid controls the frequency and amplitude of the PV inverter output voltage.

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.
