Abstract As the core element for electrical energy traceability, AC power standards play a crucial role in ensuring fair and equitable electrical energy trade settlement. The methods commonly used to construct high-precision AC power standards and the related traceability paths are summarized. The major measurement uncertainty components during the calibration of the electric energy meters via different the AC power standards are analyzed. By reviewing the technical aspects in existing AC power standards and the new requirements of power system measurement, the future development trends for electric power and energy standards are prospected.
