Abstract
Modern electrical grids with sustainable energy sources and power electronic resources have huge metering challenges such as harmonic interference, frequency variation, and electromagnetic transients. These disturbances reduce the level of accuracy of digital power meters, phasor measurement units (PMUs), power quality (PQ) analyzers, and protective relays. This paper assesses the impact of such distortions on the reliability of a measurement and proposes a framework based on the guidelines that increases resilience. The study accumulates useful best practices, the key ones for this study being: the use of IEC 61000-4-30, PQ measurements, and IEC 61850, substation communication; then the use of an accurate timing, which is a key aspect of the study, for example, the use of the time transfer protocol within the network, a standard that the PPC defines. It outlines a conceptual platform of evaluation for testing performance under harmonics, transients and timing errors. Simulation examples and block diagrams are used to illustrate the effects of these disturbances on the accuracy of measurements and recommend corrective measures. The results show that a combination of coordinated filtering, accurate time synchronization, standardized communication and hardening the environment, enhance the dependability of measurements in renewable rich smart grids.
