Urbanization induces shifts in surface environmental factors, including impervious surface expansion, green space loss, and temperature increase in which the extreme temperature is supposed to significantly raise total electricity consumption (TEC) in urban areas. Applying remote sensing data and data analysis, this study aims to explore relationships between urbanization, surface environmental factors (SEF), and electricity consumption (EC). The relevance of surface temperature and total electricity consumption was also considered. The research found the disturbance of SEF through changes in vegetation index, urban index, and surface temperature. The vegetation was detected to be narrowed while the impervious surface and land surface temperature had the same trend of rising. These tendencies correspond to the urbanization process in the Bangkok Metropolitan Area (BMA). The urbanization process was also detected by extension of customers and electricity consumption, mainly in industrial sectors and household consumption. The number of users in industrial sectors well explained total consumption. Besides, the surface environmental factors jointly contributed to the consumption in the residential sector. Urban expansion assessed by urban index has more contribution to electricity utilization compared to surface temperature. These findings proved that the total consumption originated from the industrial sectors, especially the medium and large scales. These outcomes can serve the electrical business in order to provide adequate and improve service quality.
城市化导致地表环境因素发生变化,包括不透水面扩张、绿地减少和温度升高,其中极端温度预计会显著增加城市地区的总用电量(TEC)。本研究应用遥感数据和数据分析,旨在探讨城市化、地表环境因素(SEF)和电力消耗(EC)之间的关系。还考虑了地表温度与总耗电量之间的相关性。研究发现,通过植被指数、城市指数和地表温度的变化,SEF 受到干扰。植被面积缩小,而不透水面和地表温度呈上升趋势。这些趋势与曼谷大都市区(BMA)的城市化进程相对应。城市化进程还通过客户和用电量的扩展来检测,主要集中在工业部门和家庭消费。工业部门的用户数量很好地解释了总消费。此外,地表环境因素共同促成了住宅部门的消费。城市指数评估的城市扩张对电力利用的贡献大于地表温度。这些发现证明,总消耗量来自工业部门,尤其是中型和大型工业部门。这些结果可以为电力企业服务,以提供足够的电力并提高服务质量。
