The inverter is the heart of every PV plant; it converts direct current of the PV modules into grid-compliant alternating current and feeds this into the public grid. At the same time, it controls and monitors the entire plant.
The rated capacity of the PV array may be up to ten percent above the rated capacity of the inverter. If an inverter is greatly undersized, this can have a negative effect on plant yield, since the inverter can no longer process part of the module power supplied during periods of high radiation.
One-phase inverters are usually used in small plants, in large PV plants either a network consisting of several one-phase inverters or three-phase inverters have to be used on account of the unbalanced load of 4.6 kVA.
Because PV modules are always live when light is shining on them, they cannot be switched off. If the inverter cable is disconnected during operation, this can lead to dangerous light arcs forming, which do not go out on account of the direct current.
This paper proposes a universal control (UniCon) scheme for grid-connected inverters that allows operation in grid-following and grid-forming modes. The inverter does not need detailed
