Grid Integration of Single-Phase Inverters Using a Robust PLL
In this paper, a PLL-less control technique for single-phase grid-connected voltage source converter (VSC) system is proposed that overcomes shortcomings in traditional PLL-based
There are numerous standards defining the interconnection and disconnection of single-phase inverters to utility grid available. The solar inverters are one of the most extensively researched topics in emerging power electronics due to their variety in circuit and control architectures.
An ever-increasing interest on integrating solar power to utility grid exists due to wide use of renewable energy sources and distributed generation. The grid-connected solar inverters that are the key devices interfacing solar power plant with utility play crucial role in this situation.
As a summary of discussions, the multi-stage single-phase PV inverters are required to be improved in terms of power decoupling, efficiency under partial shading, operation mode control of converter stage, grid-connection and islanding detection of unfolding stage, and device topologies to eliminate potential hazards of transformerless operation.
Therefore, grid side controller of solar inverter should meet grid interconnection requirements, provide secure grounding, and power decoupling features. The inverters improved for operating in single-phase grids should comply with grid requirements described by several international and regional standards.
