This dependency leads to fluctuations in power output and potential grid instability. Grid-connected inverters (GCIs) have emerged as a critical technology addressing these challenges. GCIs convert variable direct current (DC) power from renewable sources into alternating current (AC) power suitable for grid consumption .
The multi-frequency grid-connected inverter topology is designed to improve power density and grid current quality while addressing the trade-off between switching frequency and power losses . Traditional grid-connected inverters rely on power filters to meet harmonic standards, but these filters increase system complexity, cost, and size.
Unlike conventional fossil-fuel-based power plants, RESs generate power that depends heavily on environmental conditions. This dependency leads to fluctuations in power output and potential grid instability. Grid-connected inverters (GCIs) have emerged as a critical technology addressing these challenges.
Additionally, novel PV inverter control techniques ensure stable operation during unbalanced grid conditions using 4-leg NPC inverters, instantaneous active/reactive control, and hardware-based solutions. Table 16 provides a comparative analysis of these control strategies.
