Designing Resilient Microgrids: An Energy-Storage Centric Approach
Abstract
Military operations increasingly rely on tactical microgrids to ensure energy resilience, operational flexibility, and mission success in dynamic environments. Lithium iron phosphate battery (or LFP battery) presents promising opportunities for enhancing the performance and sustainability of military energy systems. This research aims to investigate the utilization of LFP batteries in military tactical microgrids, addressing key challenges and optimizing their integration to support critical operations.The objective of the proposed investigation is to develop a framework combining first-principal models, usage-dependent experimental data, and data-driven modeling and control augmentation to create an intelligent built-in battery monitoring system that can be deployed on Energy Storage Systems (ESS) for resilient microgrid applications. The expected outcome of the proposed project includes a suite of experimental battery data, electrochemical models, and control algorithms with online learning capabilities.This hybrid system will not only utilize data-driven insights for immediate control adjustments but also refine its model-based predictions, ensuring continuous evolution and optimization of the Battery Management System (BMS). Such a system will significantly enhance State of Charge (SoC) and State of Health (SoH) estimations, extend battery life, and improve safety measures, thereby facilitating more efficient and reliable utilization of battery ESS for microgrids. Moreover, throughout the duration of the project, data preparation and holistic experimental data and diagnostic tests of LFP battery under micro-grid use cases with formulation of in-situ diagnostic tests for internal state determination will be conducted to support the model development and validation.Through the execution of this action plan, our objective is to advance the knowledge and technology surrounding battery ESS for microgrids. By addressing the challenges of degradation and state determination under variable conditions, we aim to significantly improve the performance and reliability of these critical energy storage solutions, thereby improving the resilience and reliability of US Navy microgrids.Approved for Public Release.
