This control strategy involves adjusting the active power output of the PV inverters based on the local voltage levels. When the voltage at the PCC exceeds a certain threshold, the PV inverter reduces its power output to prevent further voltage rise and maintain the voltage within acceptable limits.
By optimizing the reactive power (Volt/VAr) control of smart inverters for photovoltaic (PV) systems, the method not only prevents voltage violations but also ensures that the necessary curtailment of power is fairly distributed among all PV inverters.
The control’s regulatory effect is constrained by the PV generation variability and the inherently limited curtailment scope for each inverter, which can result in uneven voltage regulation across different network segments.
PV inverters located closer to the substation experience a smaller voltage rise compared to those further away. This is due to the lower impedance and resistance of the distribution lines closer to the substation, which results in less voltage drop and hence less voltage rise.
The operation of various PV inverters (PVIs) within the same low-voltage distribution network, under a local control scheme, encounters a challenge related to the standardization of the volt-watt curve for all PVIs, as mandated by regulations such as IEEE Std 1547.2018 (Gholami et al., 2022, Jafari et al., 2022).
Nonetheless, the main disadvantage for prosumers is the income loss as a result of power outages. Notwithstanding this expensive drawback, it is crucial to remember that the PV inverters (PVIs) would trip immediately owing to protective measures in cases with high overvoltage levels.
