Abstract: In the context of the rapidly growing distributed generation sector, two prominent issues have emerged: excessive line losses caused by improper placement of settlement metering points outside the property boundary, and metering errors resulting from discrepancies between assumed and actual energy consumption methods.This paper presents two case studies that analyze the causes and implications of these problems, offering calculation methodologies and corresponding solutions. The findings provide valuable insights to support provincial power grid companies in achieving their objectives of improving service quality and operational efficiency.
