Guest Editorial Special Issue on Power Quality in Smart Grids

Smart grid (SG) is usually described as a power system utilizing information and communication technology (ICT) and advanced monitoring systems to improve the grid performance and offer a wide range of additional services for the consumers. Some of the main features of such a grid are self-healing from power disturbances, efficient energy management, automation based on ICT and advanced metering infrastructures (smart metering), integration of distributed power generation, renewable energy resources and storage units as well as high power quality and reliability. In this regard, the concept of microgrid is brought to the stage as one of the main building blocks of the future SGs.
