The way the “smart grid” is operated certainly helps improve reliability but the impact on power quality is more complex. Sometimes the smart grid provides better quality power supply but the presence of power electronics, for example as an interface for load and distributed generation, increases the level of emissions affecting the power quality. Technical solutions such as microgrids will present new challenges for the control of harmonics, frequency variations and system stability. Advanced distribution automation applications such as VVC+VVO, fault location, feeder reconfiguration and demand side management may contribute to the number of sags and swells occurring on the grid, to the voltage unbalance on distribution feeders. New types of disturbances (supraharmonics) and a more efficient and comprehensive way of evaluating the power quality will require new indices and updating old ones. In this type of grid, the information and its accuracy is essential and that will require more performing sensors and IEDs, more leverage of the existing ones and implicitly new measurement techniques. Intelligent meters, controllers, relays and PMUs are capable to measure power quality even if some of them do not comply with a class A devices, and convincing the manufacturers that progress needs to be made in implementing existing standards for the measurement of PQ is an achievable task. This panel will include a discussion of these issues, as well as a presentation on the activities of the CIGRE/CIRED Working Group on these topics.
