本文提出了一种稳健的建筑能源管理系统(BEMS)，以促进可再生能源(RES)集成建筑中的多种(热能和电力)能量流动。拟议的BEMS旨在优化调度建筑部件，以抵消由于RE和电气负载而在实时运营中遇到的运营不确定性。由于建筑构件的响应时间不同，BEMS在时间上被分解为两个时间尺度。在较长的时间尺度(提前一小时)中，基于燃料电池的微型联合制冷、供热和发电单元、储能系统和热负荷控制被调度，而在较短的时间尺度(提前15分钟)，电池能量存储被重新调度，电力需求响应被激活。多时间尺度的协调是通过双层优化框架实现的，其中两阶段稳健优化(TSRO)模型优化系统运行，以实现上层任何级别的不确定性。在实际系统运行过程中，通过较低层次的优化来计算资源决策。大量的仿真结果表明，所提出的方案在保证可靠运行和用户舒适性的同时，能够稳健地处理不确定性。
This article proposes a robust building energy management system (BEMS) for facilitating multiple (thermal and electrical) energy flows in renewable energy sources (RES) integrated buildings. The proposed BEMS aims to optimally dispatch building components to counteract operational uncertainties encountered in real-time operation due to RES and electrical load. Owing to different response times of building components, BEMS has been time-decomposed into two timescales. In the longer timescale (hourly-ahead), fuel cell-based micro-combined cooling, heating and power unit, energy storage systems and thermal load control are dispatched, while in the shorter timescale (15-min ahead), battery energy storage is re-dispatched and electrical demand response is activated. Multi-timescale coordination is achieved through a bi-level optimization framework, where a two-stage robust optimization (TSRO) model optimizes system operation for realization of any level of uncertainty in the upper level. A recourse decision is computed by lower-level optimization during actual system operation. Extensive simulation results demonstrate effectiveness of the proposed scheme to robustly handle uncertainties while ensuring reliable operation and user-comfort.
