Power quality issues are becoming more essential for power companies. Existing power quality standards are described by stable or transient states of current and voltage, from a perspective of power supply. In practice, it is up to customers’ sensitivity and actual experiences for evaluation of power quality. In this work, power experience is proposed as a composite criterion of both existing power quality standard and related customers’ information. From a perspective of customers’ experience, the concept, features, and standards are proposed for power quality of experience. A case stu
