(625e) Multiscale Integration for Sustainable and Resilient Distributed Energy Systems (DESs)

Decentralized energy systems provide one potential pathway towards more resilient, and sustainable energy systems for the future [1]. This can be realized through building a network of small-scale, geographically-distributed energy production facilities that are connected with associated suppliers, intermediaries, and end users by relevant transportation links and modes, also known as a distributed energy system (DES) [2, 3]. Consistent service level is crucial in DESs, hence it is highly desirable to build a resilient system that has the capability to prepare for unexpected events, respond to disruptions, and recover from them as quickly as possible. A major bottleneck in designing resilient DESs is the lack of understanding on the impact of lower-level decisions on overall system resilience. To that end, a multiscale systems engineering approach may be utilized to integrate decision-making across various scales of operation [3].

In this work, we present the foundations of a multiscale framework for the analysis and design of cost-effective and resilient DESs. Specifically, we integrate: 1) facility location decisions considering system resilience through the use of a resilience metric; 2) process synthesis using modular process units; and 3) considerations of multiple objectives such as economic efficiency and environmental sustainability. The proposed framework demonstrates the potential for enhancing the resilience of DESs through targeted, cost-effective strategies across multiple scales. To illustrate the applicability of the framework, we present a study on the Texas-Louisiana hydrogen grid. (230 words/1500)
