Deciphering domestic energy demand through household electricity and gas consumption
摘要
Abstract
This study investigates residential electricity and gas demand in Iraq using smart meter data from 15
000 households between 2019 and 2023. The primary objective is to analyze temporal energy consumption patterns
focusing on the impact of environmental
behavioral
and household-specific factors. The results show that electricity consumption peaks during the afternoon
particularly between 12:00 and 14:00
with average usage reaching 2.3 to 2.6 kWh
while gas consumption increases in the winter months
especially in the early morning hours
driven by heating and cooking activities. The analysis of weekend versus weekday consumption reveals a 6.4 % increase in electricity and a 3.1 % rise in gas usage on weekends
indicating shifts in behavioral energy usage patterns. The study finds that predicted values closely match observed data
with a deviation of only 5 % for electricity and 7 % for gas
showcasing high model accuracy. The concept of "variability" is clarified as fluctuations in demand across different times of the day
which were reduced in households with efficient appliances
as identified from household energy audits linked to smart meters. The dataset also provides insights into the use of energy-efficient appliances
collected from utility-linked surveys and integrated household registration data. The findings offer valuable insights into demand-side energy management and are particularly relevant to urban Iraqi households but may also inform demand forecasting in similar regions with comparable climates and energy use behaviors.
