Abstract:
The rapid global proliferation of grid connected and stand alone photovoltaic (PV) arrays has pushed the renewable energy conversation beyond raw kilowatt hours toward the subtler but critical issue of power quality (PQ). While sunlight is free, the conversion chain from panel to pointofcommon coupling is anything but benign: high frequency switching injects current harmonics, partial shading provokes low order voltage distortion, fast irradiance ramps create flicker, and unbalanced islanded operation destabilizes frequency. In weak or meshed grids alike, these disturbances erode energy yield, accelerate equipment aging, and threaten regulatory compliance.
This review dissects how advanced topology controllers have become the first line of defense against such PQ degradation in modern PV systems. Drawing on 257 peer reviewed papers, industry white books, and field reports issued between January2010 and March2025, the study classifies solutions along two intertwined axes: (i) hardware topology-ranging from multilevel inverters (neutral point clamped, flying capacitor, cascaded H bridge) and transformer less H bridge derivatives that suppress common mode voltage, to hybrid active filters and DSTATCOM integrated converters; and (ii) embedded control-spanning synchronous reference frame, hysteresis, finite set model predictive, space vector modulation, and AI enhanced schemes such as fuzzy logic, adaptive neuro fuzzy inference systems, and reinforcement learning regulators.
