The Impact of Household Appliances and Devices: Consider Their Reactive Power and Power Factors

Abstract

In recent years, there has been a noticeable change in the flow of reactive power in power network systems around the world. A part of this change could be due to residential household appliances, particularly with the increasing use of LEDs and battery-powered devices with switch-mode power supplies. This study investigates the power characteristics of 56 modern appliances and devices. The results indicate a major change in the electrical behavior across these household appliances and devices. In particular, LED technology and switch mode power supplies are likely to increase household reactive power injection, which will increase as penetration of these products grows, particularly with government programs often incentivizing their uptake. A variety of avenues are available to address these issues, including governments requiring appliance manufacturers to display the power factor of their appliances or device. In time, appliance manufacturers may develop new products that have built-in power factor correction. Overall, the findings highlight how efforts to be sustainable with energy use may have unintended consequences on other parts of the electrical system that need to be considered for the sustainability of the system as a whole.

Monitoring Energy and Power Quality of the Loads in a Microgrid Laboratory Using Smart Meters

“…For example, Figure 3 shows the energy generated by the photovoltaic system within one week, where it can be observed that solar intensity varies periodically, as indicated by the recurring patterns. Focusing on load analysis, most published articles tend to focus on measuring active power, although various authors have proposed the analysis of reactive power as part of future work [28], which is a critical variable in real systems [44]. In fact, some recent surveys have highlighted the importance of maintaining a balance between active and reactive power to ensure power quality in microgrids [45].…”

Real-Time Energy Management in Smart Homes Through Deep Reinforcement Learning

“…The current data on energy frameworks indicates that reactive power accounts for approximately 15% to over 40% of a household's total energy consumption [39][40]. With the increasing adoption of renewable energy sources, ES systems, and EVs, this scenario presents a notable challenge.…”
