This review paper provides a comprehensive overview of grid-connected inverters and control methods tailored to address unbalanced grid conditions. Beginning with an introduction to the fundamentals of grid-connected inverters, the paper elucidates the impact of unbalanced grid voltages on their performance.
At this point the inverter must either de-rate or shut down to comply with the standards. This can result in a situation where the grid voltage is complaint at 253 Volts, the AC wiring is complaint at 2% voltage rise, and the inverter is compliant at 258 volts. But the inverter is switching off or reducing power.
Beginning with an introduction to the fundamentals of grid-connected inverters, the paper elucidates the impact of unbalanced grid voltages on their performance. Various control strategies, including voltage and current control methods, are examined in detail, highlighting their strengths and limitations in mitigating the effects of grid imbalance.
If the grid voltage or grid frequency exceeds the thresholds specified by the grid operator, the grid-tied inverters must stop to feed in alternating current and disconnect from the utility grid in accordance with local standards and directives. Inverters are also able to modulate their output power to support the utility grid interactively.
