Abstract: The integration of photovoltaic (PV) systems into weak-grid environments presents unique challenges to the stability of grid-connected inverters. This review provides a comprehensive overview of the research efforts focused on investigating the stability of PV grid-connected inverters that operate under weak grid 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. GCIs convert variable direct current (DC) power from renewable sources into alternating current (AC) power suitable for grid consumption .
Compatibility Issue: The compatibility of next-generation inverters with present grid infrastructure is an important factor in power system modernization, especially when incorporating renewable energy sources.
Initially, the present state of the inverter technology with its current challenges against grid resilience has been investigated in this paper.
