Abstract

Driven by the rapidly growing application of distributed generation (DG) and DG based user-side microgrid, bidirectional power flow between user and power grid forces the traditional measuring method to be changed accordingly. Bidirectional metering demand of user-side microgrid and user with DGs and independent metering issues of DGs are analyzed in this paper. The impact of power quality issues caused by the integration of DGs, such as harmonic wave, voltage sag, temporary shortage and voltage flicker, on the inaccuracy of metering system are sorted out. Present situation and developing tendency of communication interface, protocol and precise metering algorithm for smart meters are summarized with introduction of smart meter’s application in future smart grid. The development tendency and modes of bidirectional metering are presented.

Key words
