分布式能源(DER)的日益普及对电网交互式高效建筑(GEB)的灵活,高效和可靠运行产生了越来越大的影响。此外,DER,建筑物和配电网络的优化和控制由于它们的相互连接而变得更加复杂。在这封信中,我们利用负载侧的灵活性和清洁能源资源开发一种新的两级混合分散-集中(HDC)算法来控制DER连接的GEB。所提出的HDC 1)实现了关于.大量的电网连接的建筑物和设备,2)结合两级设计,其中聚合器集中控制建筑物,并且系统运营商以分散的方式协调配电网络,以及3)提高计算效率并增强与异构时间尺度的通信兼容性。以美国橡树岭国家实验室的一栋办公楼为原型进行了仿真,结果表明了所提方法的有效性。
The flexible, efficient, and reliable operation of grid-interactive efficient buildings (GEBs) is increasingly impacted by the growing penetration of distributed energy resources (DERs). Besides, the optimization and control of DERs, buildings, and distribution networks are further complicated by their interconnections. In this letter, we exploit load-side flexibility and clean energy resources to develop a novel two-level hybrid decentralized-centralized (HDC) algorithm to control DER-connected GEBs. The proposed HDC 1) achieves scalability w.r.t. a large number of grid-connected buildings and devices, 2) incorporates a two-level design where aggregators control buildings centrally and the system operator coordinates the distribution network in a decentralized fashion, and 3) improves the computing efficiency and enhances communicating compatibility with heterogeneous temporal scales. Simulations are conducted based on the prototype of an office building at the Oak Ridge National Laboratory to show the efficiency and efficacy of the proposed approach.
