The future electricity grid requires smart features like flexible, accessible, reliable, and
quality power supply. These features are effectively offered by the smart grid system. The
components of the smart grid include renewable sources and controllable loads. Due to the
controllable feature of the load, various changes occur with respect to the voltage values
and harmonics. Therefore, power quality (PQ) issues with respect to smart grids become a
major topic is explained. This chapter includes the PQ issues and its effects in AC microgrids …
