PMU-based metrics for Power Quality Assessment in Distributed Sensor Networks

Abstract

In modern power systems, the measurement infrastructure represents the backbone of any monitoring and control application. Indeed, the everincreasing penetration of renewable energy sources and distributed generation has produced an operating scenario prone to instability and rapid variations. Power quality assessment procedures must evolve in order to address these challenges. In this regard, the use of phasor measurement units (PMUs), which measure the phasor values of current and voltage with high precision time stamp, presents a significant opportunity to evolve current power quality assessment procedures. This position paper suggests the inclusion of novel PMU-based metrics in order to extend quality power assessment procedures at each sensitive network node towards the further use of aggregated data at both local and/or central level. The proposed PMU-based metrics will provide a better description of the behavior of the system, allowing to take control actions as part of the extended quality power assessment procedures.
