The industry standard that addresses frequency settings for solar PV is IEEE standard 1547, Interconnecting Distributed Resources With Electric Power Systems, which specifies that (for 60 Hz systems): Certain commercial PV inverters are equipped with extended frequency ride-through capability that will not trip until frequency drops below 55 Hz.
In most regions, the standard inverter frequency for AC power systems is 50 or 60 Hz, representing the number of complete cycles per second. This inverter frequency is essential for the proper functioning of electrical devices and systems, as it dictates the speed at which motors rotate, lights flicker, and electronic components operate. 2.
Certain commercial PV inverters are equipped with extended frequency ride-through capability that will not trip until frequency drops below 55 Hz. The operating range for a typical 60-Hz small grid is within 0.2-0.3 Hz during normal operations, with no contingencies. This gives a lower frequency range between 59.7 to 59.8 Hz.
The crux of the present issue relates to the frequency ride-through settings and capability for commercial PV inverters. The industry standard that addresses frequency settings for solar PV is IEEE standard 1547, Interconnecting Distributed Resources With Electric Power Systems, which specifies that (for 60 Hz systems):
Conversely most of the PV inverters are designed to operate in the maximum power point (MPP) to generate the maximum revenue. Due to the synchronization mechanism, an inherent close coupling exists between the speed of the conventional generator and the grid frequency. On the contrary, the inverter interface completely decouples PV from the grid.
