Abstract

Resilience analysis is gaining focus, but no extensive research exists for commercial buildings. This research presents the results of a novel analysis of the resiliency in commercial buildings by examining the relationship between electric microgrids, Distributed Energy Resources (DERs), and Battery Energy Storage Systems (BESS). As energy systems face increasing challenges, including extreme weather events and grid vulnerabilities, integrating microgrids, DERs, and BESS has emerged as a promising solution to strengthen the resilience of commercial buildings. Microgrids can harness renewable energy sources and reduce environmental impacts when integrated with DERs. Most literature studies focus on residential or commercial buildings with peak-valley tariffs and simplified electrical market models. In contrast, this study focuses on BESS’ pivotal role in DER output and ensuring uninterrupted power during grid disruptions and presents an innovative approach to analyzing resilience in commercial building microgrids and an economic optimization of commercial building microgrids with Time of Use tariffs utilizing DERS and BESS. The analysis includes the technical aspects of BESS integration and control strategies that optimize their operation. It also studies the economic and environmental benefits of microgrids, DERs, and BESS, focusing on cost savings, greenhouse gas emission reductions, and grid support services.

通过采用分布式能源和电池储能系统的微电网增强商业建筑的复原力

抗灾能力分析日益受到关注，但目前还没有针对商业建筑的广泛研究。本研究通过考察电力微电网、分布式能源资源（DER）和电池储能系统（BESS）之间的关系，对商业建筑的抗灾能力进行了新颖的分析，并展示了分析结果。随着能源系统面临极端天气事件和电网脆弱性等日益严峻的挑战，整合微电网、分布式能源资源和电池储能系统已成为加强商业楼宇抗灾能力的可行解决方案。微电网与 DER 集成后，可以利用可再生能源并减少对环境的影响。大多数文献研究的重点是采用峰谷电价和简化电力市场模型的住宅或商业建筑。相比之下，本研究重点关注 BESS 在 DER 输出和确保电网中断期间不间断供电方面的关键作用，并提出了一种创新方法来分析商业建筑微电网的恢复能力，以及利用 DERS 和 BESS 的使用时间电价对商业建筑微电网进行经济优化。分析包括 BESS 集成的技术方面以及优化其运行的控制策略。它还研究了微电网、DER 和 BESS 的经济和环境效益，重点关注成本节约、温室气体减排和电网支持服务。
