由于城市化，建筑相关活动的电力需求正在稳步增加。再加上可再生能源的日益普及，这一趋势给配电网运营商在维持节点电压和最大限度地减少有功功率损耗方面带来了新的挑战。与此同时，建筑运营商需要更有效的方法来降低建筑运营成本。因此，作为智慧城市的关键一步，必须优化管理和协调建筑和配电网络的资源，以提高整个系统的效率和可靠性。为此，本文开发了一种用于建筑物到配电网络（B2DN）集成的新颖框架。该框架将商业、住宅建筑和分布式能源（DER）（包括光伏（PV）发电和电池储能系统（BESS））与配电网络结合起来，使建筑物和配电网络能够同时优化，同时尊重建筑和配电网络的限制。所提出的 B2DN 框架通过解决二次约束二次规划 (QCQP) 问题以后退方式实现。该框架的功能在与 90、192 和 481 个建筑物和 DER 集成的 IEEE 13、33 和 SB 129 节点配电网络上得到了演示。仿真结果表明，与建筑物和配电网独立管理的解耦设计相比，B2DN 控制器成功地最大限度地减少了配电网有功功率损耗并增强了电压调节，同时最大限度地减少了建筑能源成本并保持了居住者的舒适度。最后，不确定性分析显示，在天气变量、建筑内部热量增益和配电网节点基本需求存在随机性的情况下，B2DN 控制器的性能下降幅度很小。
Electricity demand for building-related activities is steadily increasing due to urbanization. Combined with the increasing penetration of renewable energy, this trend brings new challenges to distribution network operators in maintaining nodal voltage and minimizing active power losses. At the same time, building operators require more effective methods of reducing building operational costs. Therefore, as a critical step towards smart cities, it is imperative to optimally manage and coordinate the resources across building and power distribution networks to improve the overall system's efficiency and reliability. To this end, this paper develops a novel framework for Buildings-to-Distribution-Network (B2DN) integration. The framework couples commercial, residential buildings, and DERs, including photovoltaic (PV) generation and battery energy storage systems (BESS), with the power distribution network, enabling buildings and the distribution networks to be optimized simultaneously while respecting both building and distribution network constraints. The proposed B2DN framework is implemented in a receding horizon manner by solving a quadratically constrained quadratic programming (QCQP) problem. The framework’s capabilities are demonstrated on the IEEE 13-, 33-, and SB 129-node distribution networks integrated with 90, 192, and 481 buildings and DERs. The simulation results reveal that the B2DN controller successfully minimizes distribution network active power losses and enhances voltage regulation while at the same time minimizing building energy costs and maintaining occupant's comfort in comparison with decoupled designs, where buildings and distribution networks are independently managed. Finally, uncertainty analysis shows a minimal decrease in the B2DN controller's performance in the presence of randomness in weather variables, building internal heat gains, and distribution network nodal base demands.
