Resumen
This work analyzes the reduction of power
generation in strategies that regulate the PV ramp-rate
by using inverter limitation. Although the operating

This work analyzes the reduction of power
generation in strategies that regulate the PV ramp-rate
by using inverter limitation. Although the operating
principle implies some energy production losses, not
all these losses are necessary. Three different strategies
were simulated using experimental 5-second data collected throughout a year at a 38.6 MW PV plant, and
their energy losses were obtained for different ramprate levels. An improvement in one of these strategies
is proposed and evaluated. The main findings suggest
that the proposed modification has the potential to
drastically reduce annual production losses to insignificant levels. Regardless of the ramp-rate constrain,
simulation results evidenced energy losses bellow 1%. [--]
