What are power quality issues in a single-phase microgrid?
Power quality issues of concern in single-phase microgrids include voltage/frequency fluctuations, reactive power exchange and voltage/current harmonic distortion. Power quality issues in islanded operation have attracted attention recently since the effects of these phenomena are more pronounced due to the lack of stiffness of the electrical grid.
Can emerging Grid technologies improve power quality in single-phase microgrids?
However, the power-based approach was mainly considered for devices in three-phase environments and thus shall not be considered further in this review. Emerging grid technologies could also provide an alternative solution to improve power quality issues in single-phase microgrids.
What is a microgrid & how does it work?
Microgrids consist of multiple inverter-interfaced DG units, which supply local loads with active and reactive powers. Power quality issues in islanded single-phase microgrids are more pronounced due to the lack of stiffness of the electrical grid.
Why do we need LV microgrids?
The formation of LV microgrids enables to achieve high-energy efficiency and improve the reliability of the electrical supply. However, the combined power which is injected by the DG units into the grid can cause power quality issues, particularly during islanded operation.
