Benchmarking of power quality performance in transmission systems

As utility ownership evolves and technology changes the nature and role of transmission systems, there is a need for many aspects of system performance to become more transparent. Power quality (PQ) is one such area. It is becoming more relevant and desirable to understand system performance in terms of power quality, to be able to assess PQ management by the network operator and to track and infer the impacts that changes in the regulatory and investment regime have on PQ performance. The challenges and “benchmarking” of PQ performance on the system level is the subject of the work presented.
