An overview of PMU-based Electrical Power Systems modelling for Power Quality enhancement

The increasingly important use of renewable energy resources within the electricity networks has changed the paradigm of electrical power system operation. This shift is enforced by the ever-present power electronic devices, which are used both at generation side, as well as on the consumption side, cluttering the normal operation, and issuing new threats from power quality point of view. However, the new technology involved in the advanced metering systems, such as Phasor Measurement Units (PMUs), is helping both transmission and distribution operators to efficiently manage the electrical system, by correctly identify the upcoming threats for a priori calculations, as well as the causes which may have led to faults, for a posteriori evaluation. This paper deals with the widespread use of PMU-based advanced metering systems.
