The effect of appliance energy efficiency improvements on domestic electric loads in European households
چکیده انگلیسی

Across Europe domestic electricity consumption is on the rise. In an attempt to counter this increase, various initiatives have been introduced to promote the replacement of less energy-efficient appliances with more efficient ones. Whilst the likely aggregate effect of such measures over long time periods has been modelled extensively, little is known about the affect that a change to higher efficiency appliances will have on the electrical demand profile of individual households at higher temporal resolutions. To address this issue a means by which established approaches to detailed electrical demand modelling can be adapted to simulate the improvements in the efficiency of appliances is elaborated in this paper. A process is developed by which low-resolution empirical appliance demand data can be transformed to produce high-resolution electrical demand data for different periods in the year, factoring in improvements in appliance performance. The process is applied to simulate the effects a changeover to more energy-efficient appliances would have on the minute resolution demand profiles of a group of households. Results indicate that improving the energy-efficiency of appliances in households leads to a significant reduction in electrical energy requirements but does not appear to have a significant affect on the peak electrical demand.


► Low to high-resolution electrical demand transformation technique.
► Includes method to account for effects of appliance energy-efficiency improvements.
► Technique applied to simulate effect on the demand of a group of households.
► Energy-efficient appliances beneficial in reducing electrical energy consumption.
► Energy-efficiency alone not necessarily effective in reducing peak power demands.
