Household appliances represent substantial electricity load within the residential sector, particularly during the electricity system's period of peak evening load. While there is broad understanding of the factors that systematically impact on aggregate residential loads, much less is known about appliance loads. A research priority is understanding how socio-demographic, dwelling, and appliance factors are associated with the timing and scale of appliance loads. Using data from Ireland the analysis finds that the number of household occupants; number of appliances; and daytime occupancy of the home are closely associated with appliance loads but varies depending on the time of day. No association is found between appliance uses and building tenure, type or age; or socio-demographic variables such as income, age or education. The empirical findings have relevance for modelling residential electricity loads, and for design of measures to shift residential loads away from the evening peak period.
家用电器在住宅部门中代表着大量的电力负荷，尤其是在电力系统晚间负荷高峰期。虽然人们对系统性影响住宅总负荷的因素有广泛的了解，但对电器负荷的了解却少得多。一个研究重点是了解社会人口统计学、住宅和电器因素如何与电器负荷的时间和规模相关联。利用来自爱尔兰的数据进行分析发现，家庭居住人数、电器数量以及房屋白天的居住情况与电器负荷密切相关，但会因一天中的时间而有所不同。未发现电器使用与房屋保有期限、类型或年龄；或收入、年龄或教育等社会人口统计学变量之间存在关联。这些实证研究结果对于模拟住宅电力负荷以及设计将住宅负荷从晚间高峰期转移的措施具有重要意义。
