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.
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.
A micro inverter operating in grid-connected mode should satisfy the grid connection standards in terms of power quality, THD ratios, islanding detection, grid interfacing limits for voltage and frequency, and grounding.
On the other hand, grid side control is requested to improve power quality and efficiency of inverter to ensure reliable operation. Therefore, grid side controller of solar inverter should meet grid interconnection requirements, provide secure grounding, and power decoupling features.
