Abstract

Standby power consumed by power supplies is considered as “ vampires” for its invisible and useless electricity consumption. No method were proposed to estimate the exact volume of from users’ power consumption data.

This article proposes a standby power consumption estimating method using frequency analysis and high frequency denoising. A signal decomposition analysis has been implemented in power supply data and rigorous mathematical derivation has been conducted to get the average standby power.

Standby power consumption, like vampires sucking blood, often takes place unnoticeably, the negligence of which often leads to intangible energy waste.

Standby power consumption typically refers to the power consumed by electrical devices that cannot be switched off completely without being unplugged or not providing their primary services, such as some industry machines, TVs, microwave ovens, air conditioners, etc. These products often draw power 24 hours a day without the awareness of the consumer. This invisible power is consumed by power supplies converting AC into DC, the sensors and circuits needed to receive remote signal, soft keypads and displays, or the device circuits that continue to be energized even

when the power is off.


Business Value

The increasing number of electric utilities makes standby power consumption no longer negligible

with respect to the total electricity consumption of the industry or households.

Several studies have documented that standby power loss averages between 20W to 90W per home, ranging from 4% to 14% of total residential electricity use in different countries.

Standby power consumption varies with different users and with different application apparatus ,

which makes the measurement of standby losses difficult
