Power Quality Concerns in Implementing Smart Distribution-Grid Applications

This paper maps the expected and possible adverse consequences for power quality of introducing several smart distribution-grid technologies and applications. The material presented in this paper is the result of discussions in an international CIGRE-CIRED joint working group. The following technologies and applications are discussed: 1) microgrids; 2) advanced voltage control; 3) feeder reconfiguration; and 4) demand-side management. Recommendations are given based on the mapping

Current practice and future challenges for power quality monitoring - CIGRE WG C4.112 perspective

This paper describes the initial activities of the recently created CIGRE WG C4.112 Guidelines for Power quality monitoring - measurement locations, processing and presentation of data . The WG was created in January 2011 in recognition of demand for coherent set of guidelines for power quality monitoring in existing and future power networks to meet increasing customers' and the regulatory agencies' demands to provide information on the actual power quality level in power networks. Though still at early stages of the work the members of the WG compiled an extensive material about the state of the art of power quality monitoring. This paper summarizes current understanding of power quality monitoring issues and points out directions in which the WG will continue to work over next couple of years in order to provide answers to outstanding questions
