20 Voltage Regulation System (VRS) The PV facility shall contribute to the grid s voltage regulation, following the settings and reference of the utility s operator with a continuously variable and acting close loop. Frequency Ride-Through The frequency protection will be set under PREPA requirements. Voltage Ride-Through The generators shall be online despite of the presence of voltage sags (LVRT) and Overvoltage (OVRT) in the grid. Power Ramp Rate control The PV facility shall be able to control the rate of change of power output during some circumstances. The maximum change allowable is 10% of the rated power per minute. PV plant has to reduce power under utility demands (curtailment). Frequency response/regulation PV facility should response like a classical governor due to primary frequency regulation. Reactive Power Capability The total power factor shall be from 0.85 lagging to 0.85 leading at the point of interconnection (POI). The aim is that PVF can ramp the reactive power from 0.85 lagging to 0.85, leading, in smooth continuous fashion, at the POI. 33
