Electrical Propulsion Drive Systems with Hybrid Energy Storage: Control and Optimization
Abstract
ABSTRACT The goal of this proposal is to develop advanced energy storage concepts and control solutions for electrical propulsion systems with improved system efficiency and reliability through integrated hardware design and control optimization. By investigating optimal energy storage configuration and distribution, we seek new control solutions and system integration tools to enable the next generation electrical propulsion system design to minimize energy storage requirements, maximize energy savings, and reduce component wear. In ONR Grant N00014-11- 1-0831 (Energy Cycling and Efficiency Improvement for Electrical Propulsion Systems with Hybrid Energy Storage), we have taken a four-pronged approach to this problem that combined model development, model-based design and analysis, test-bed construction, and hardwaresupported validation, towards the development of a highly-efficient electrical propulsion drive system. Four major tasks were pursued to achieve a comprehensive solution: the development of system models and numerical tools; model-based system design and sensitivity analysis; hardware development to construct the test-bed and establish control rapid-prototyping capabilities; hardware implementation and control validation. This proposed two-year project seeks to complete the work proposed in N00014-11-1-0831 (which has one year left and $250,363 final incremental fund not provided), and extends our investigations by adding flywheel energy storage to the originally-considered battery and ultracapacitor hybrid energy storage systems (HESS). The proposed research will also focus on investigating dynamic interactions among power generation, energy storage, and variable speed drive subsystems of electric propulsion systems equipped with hybrid energy storage. The investigation of the flywheel/battery hybrid energy storage option will be carried out to characterize its dynamic capabilities and control implications, in comparison with the ultracapacitor/ battery HESS solutions. The dynamic characteristics of the integrated system and source-load interactions will be the foundation for developing the control and optimization solutions, using energy storage as active control devices, to ensure improved energy efficiency and to mitigate unintended interactions. The control strategies developed under this project will be experimentally validated using the Electric Drive with Hybrid Energy Storage (EDHES) testbed developed at Michigan Power and Energy Laboratory with support from the ONR DURIP program. The final report of this project will include a comprehensive analysis of the impact of distributed energy storage on the shipboard power system.
