Power factor is the cosine of the phase angle in a power triangle. It is defined as the ratio between the active power (W) and the apparent power (VA). Power factor will vary between 0 and 1, and be either leading or lagging.
If all inverter power factors have converged to the synchronized point or the set point (i.e., PF1 = PF2 = · · · = PFn = PFSP), then the power factor at the PCC is PF = PFSP. A. PV Inverter Start Without loss of generality, assume that Inverter 1 is off and the remaining inverters are running and have converged to the set point.
Solar PV systems are usually near unity power factor as the output is generally in phase with the voltage. However, inconsistencies can still occur, and they need to be anticipated. This can be done using several methods, including:
Abstract—To maintain the power quality of solar farms, the common-point power factor of multiple photovoltaic (PV) inverters needs to be maintained inside of the utility requirement range. One solution is to utilize the communications capabilities of protective relays, meters, and PV inverters to integrate an active control system.
Leading power factor is expressed as a positive angle between the voltage and current waveforms in phasor representation. Lagging power factor occurs when the circuit's phase current lags behind the phase voltage. This typically occurs in circuits with inductive loads, where the current waveform lags behind the voltage waveform.
