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 .
Grid-connected microgrids, wind energy systems, and photovoltaic (PV) inverters employ various feedback, feedforward, and hybrid control techniques to optimize performance under fluctuating grid conditions.
The control law is defined as: (126) u (t) = k 1 ∣ e ∣ 1 2 sign (e) k 2 ∫ sign (e) d t Where k1 and k2 are control gains, and e represents the frequency deviation. The capacitive-coupling grid-connected inverter (CGCI) is a cost-effective alternative to inductive-coupling inverters due to its lower dc-link voltage requirements .
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.
