The Advanced Modular Power Systems (AMPS) project is infusing new technology into power systems and components and proving their capabilities through exploration-based ground demonstrations.
The AMPS technology portfolio includes the development of modular power units which, when combined with standardized interfaces, will provide commonality across a variety of exploration vehicles for future NASA missions. The project has developed the Modular Electronic Standard for Space Power Systems, which defines the form, fit, and function of each modular power unit for human exploration missions and systems.
Additionally, the AMPS technology portfolio includes the development of an autonomous power controller (APC) to manage electrical space power systems without a human operator in the loop. The APC provides 3 main functions:
The AMPS APC team is collaborating with external partners in developing the APC capability for a lunar surface based electrical power utility. A collaboration with Sandia National Laboratories is focused on managing power of the lunar electrical power utility, which is made up of smaller islanded microgrids that contain their own power generation and energy storage. This hierarchical power controller enables the sharing of power between the islanded microgrids to ensure all higher-level lunar surface objectives are met even during failure scenarios. The APC team is also working with the US Army on expandable and reconfigurable electrical microgrids that can seamlessly integrate dissimilar power sources to maximize electrical power availability. In this effort, the APC team will integrate the US Army developed Tactical Microgrid Standard (TMS) into a AMPS modular electronic unit (MEU) based power system and evaluate the ability for TMS to support evolvable and reconfigurable electrical power systems. If this effort is successful, NASA will be able to leverage additional capabilities developed under the TMS effort and take advantage of DoD supply chain in developing power system components for the lunar surface.More »
The AMPS project seeks to transform future space power system architectures with a modular approach, standardizing the power system at the electronics module level, and validating the modular approach through ground-based demonstrations. The anticipated benefits include opportunities to minimize power system maintenance operations, to improve power system availability, and to reduce the number of unique spare parts which necessary to enable sustainable future exploration missions and systems. Through the autonomous power controller effort, the AMPS project seeks to autonomously integrate dissimilar power sources to maximize power availability for lunar microgrids. This work leverages important collaborations with Sandia National Laboratories and the US Army to develop power system capabilities for a sustainable lunar presence.More »
