Smart Grids: Importance of Power Quality

The transformation from a centralized electrical grid system to a distributed electrical system via smart grids has drawn tremendous attention. Smart grids introduce new technological concepts that require interconnection between sensitive electrical and electronics components. It is important to maintain electromagnetic compatibility between these components to assure uninterrupted and high quality supply of electricity in future under deregulated grid set-up. Realization of smart grids requires balance between two main trade-offs: efficiency and reliability. Often reliability is given priority however it is not always guaranteed. Power quality is one of the important aspects responsible for smart grids reliability and should not be neglected. An adequate power quality guarantees the necessary compatibility between all equipments connected to grids. Henceforth, in this paper presents a review on smart grids structure, significance and requirement of power quality, and different levels of power quality issues in smart grids.
