合成电网为电力系统研究人员提供了大规模真实测试用例的完全可用性，而无需担心保密问题。由于许多电力系统研究需要负载信息，因此在这些综合测试用例中对总线电平变化进行建模非常重要。本文提出了一种在综合电网测试案例中进行母线级静态负载建模的方法。根据真实电网数据，为每辆公交车分配住宅、商业和工业部门的实际负荷构成比。为每种负载类型创建多个标准化模板负载曲线，并将其静态分配给每条总线。然后将负荷构成比和负荷模板组合并缩放到足迹电网，以获得全年母线级负荷曲线。该方法在 2000 总线测试案例中进行了说明，并使用公共 ERCOT 数据进行了验证。使用合成负载的机组承诺解决方案也作为应用程序提供。
Synthetic electric grids provide full availability of large-scale realistic test cases to power system researchers without confidentiality concerns. As many power system studies require load information, it is important to have bus level variation modeled in these synthetic test cases. This paper presents a methodology for bus level static load modeling in synthetic electric grid test cases. A realistic load composition ratio for residential, commercial and industrial sectors is assigned to each bus according to the real electric grid data. Multiple normalized template load curves for each load type are created and assigned statically to each bus. The load composition ratio and load templates are then combined and scaled to a footprint electric grid to obtain the bus level load curve for the whole year. The methodology is illustrated in 2000-bus test case and validated using public ERCOT data. A unit commitment solution using the synthetic load is also presented as an application.
