Abstract

In this paper

the distributed photovoltaic generation（PV）is taken as an example to analyze the reasons of power quality due to distributed generations（DGs）consuming in distribution power system.The conception of power quality disturbing power（PQDP）is proposed and defined;methods to calculate corresponding individual PQDP are also introduced. Based on PQDP conception

a kind of normalized power quality influence weight coefficient to be used for constraint the consumption of DGs is defined in terms of relevant national power quality standard limits. It is shown by the application analysis that the method proposed in this paper is feasible and can be used to identify power quality weight influenced by DGs consumption.
