End-Use Load Profiles for the U.S. Building Stock

The United States is embarking on an ambitious transition to a 100% clean energy economy by 2050, which will require improving the flexibility of electric grids. One way to achieve grid flexibility is to shed or shift demand to align with changing grid needs. To facilitate this, it is critical to understand how and when energy is used. High quality end-use load profiles (EULPs) provide this information, and can help cities, states, and utilities understand the time-sensitive value of energy efficiency, demand response, and distributed energy resources. Publicly available EULPs have traditionally had limited application because of age and incomplete geographic representation. To help fill this gap, the U.S. Department of Energy (DOE) funded a three-year project, End-Use Load Profiles for the U.S. Building Stock, that culminated in this publicly available dataset of calibrated and validated 15-minute resolution load profiles for all major residential and commercial building types and end uses, across all climate regions in the United States. These EULPs were created by calibrating the ResStock and ComStock physics-based building stock models using many different measured datasets, as described in the "Technical Report Documenting Methodology" linked in the submission.

美国正推进一项雄心勃勃的转型计划，力争在2050年前实现100%清洁能源经济，而这一目标的达成需要提升电网的运行灵活性。实现电网灵活性的途径之一是削减用电需求或转移负荷时段，以匹配不断变化的电网运行需求。为此，掌握能源的使用方式与时段分布至关重要。优质的终端用电负荷曲线（End-Use Load Profiles，EULPs）可提供此类关键信息，能够帮助城市、州级政府与公用事业企业理解能效优化、需求响应以及分布式能源资源的时效价值。传统公开可得的终端用电负荷曲线因数据年代久远、地理覆盖范围不全，应用场景十分有限。为填补这一空白，美国能源部（U.S. Department of Energy, DOE）资助了一项为期三年的项目——《美国建筑存量终端用电负荷曲线》，该项目最终产出了本公开数据集，涵盖美国所有气候区域内各类主要住宅与商业建筑类型及终端用能场景的经校准与验证的15分钟分辨率负荷曲线。如提交材料中所附的《记录方法学技术报告》所述，这些终端用电负荷曲线是通过利用多组实测数据集，对ResStock与ComStock这两款基于物理原理的建筑存量模型进行校准后生成的。
