Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
The requirements for the grid-connected inverter include; low total harmonic distortion of the currents injected into the grid, maximum power point tracking, high efficiency, and controlled power injected into the grid. The performance of the inverters connected to the grid depends mainly on the control scheme applied.
Abstract - The increase in power demand and rapid depletion of fossil fuels photovoltaic (PV) becoming more prominent source of energy. Inverter is fundamental component in grid connected PV system. The paper focus on advantages and limitations of various inverter topologies for the connection of PV panels with one or three phase grid system.
Inverter constitutes the most significant component of the grid connected photo-voltaic system. The power electronics based device, inverter inverts DC quantity from array in AC quantity as suitable to grid.
To provide voltage support at the PCC, reactive power is injected into the grid under fault conditions as per the specified grid codes. As previously discussed, the simultaneous injection of peak active power from PVs and reactive power into the grid for voltage support can trigger the over current protection mechanism in PV inverter.
However, these methods may require accurate modelling and may have higher implementation complexity. Emerging and future trends in control strategies for photovoltaic (PV) grid-connected inverters are driven by the need for increased efficiency, grid integration, flexibility, and sustainability.
