Benchmarking of power quality performance in transmission systems - CIGRE WG C4.27 perspective
This paper describes the activities of CIGRE WG C4.27 "Benchmarking of Power Quality Performance in Transmission Systems". The WG was established in December 2012 in recognition of demand for coherent set of guidelines for benchmarking power quality performance in existing and future transmission networks. During the work the members of the WG have compiled extensive material related to the state of the art of benchmarking power quality performance in transmission systems. This paper summarizes current understanding of benchmarking power quality performance issues and identifies directions in which the WG will continue to work in order to provide resolutions to outstanding questions.
