Rational selection and configuration of metering points of the distributed photovoltaic power generation into the grid network are very important to calculate the upper and lower elec-tricity accurately. This paper firstly introduces the background and the principle of the distributed photovoltaic power generation sys-tem, and then points out some problems of the distributed photovol-taic power generation into the grid network. Combined the charac-teristics of distributed photovoltaic power generation with the con-figuration principle of metering points, selection and configuration of metering points of the distributed photovoltaic power generation into high/ low voltage grid and in different operating modes have been analyzed. Finally, the principle and experimental verification of the photovoltaic stealing have been discussed, and solutions to prevent photovoltaic stealing have been also proposed in this paper.
