Acquisition of a High-Performance Controller for Advanced Electric Drive Hybrid Energy Storage Test-Bed
Abstract
This proposal seeks DoD funding to enhance the existing Michigan Power and Energy Laboratory (MPEL) Advanced Electric Drive and Hybrid Energy Storage (AEDHES) test-bed.The AEDHES consists of multiple energy storage systems (batteries, ultra-capacitors, flywheel) and their corresponding power electronic converters with electric propulsion drives (using either induction or permanent magnet machines), and supports research activities for Navy ship electrification. All power electronic converters/inverters in the test-bed are controlled by a singlecontrol system using Simulink Real-Time. This architecture permits a great degree of flexibility to implement sophisticated, coordinated control techniques which can optimize overall system performance. The acquisition of the equipment will enhance our existing studies into ship electrification by allowing the investigation of sophisticated control techniques, such as Model Predictive Control (MPC). It will also allow real-time interaction of the test-bed hardware with sophisticated dynamic models of other ship systems, such as hydrodynamic models of ship propulsion and DC Zonal Electric Distribution Systems (DC ZEDS). Such an approach will allow the experimental validation of control strategies for electric drives and hybrid energy storage systems under conditions associated with actual ship behavior.The equipment requested herein is a high-performance control system, manufactured by Opal- RT. The high-performance control system will utilize a combination of microprocessors and FPGAs to synthesize control algorithms, thereby achieving quick response time with substantial computational capacity. The real-time digital simulator will possess a large number of cores, with different aspects of the control algorithms/system simulations to be processed in parallel.We will also request additional power electronic converters to extend the capabilities of the testbed (e.g., to give the test-bed the ability to dump excess power back onto the utility grid), as well as provide replacement components.
