Holomorphic Embedded Load Flow for Autonomous Spacecraft Power Systems, Phase II Project

Project Introduction

The proposed innovation advances the ability to apply the Holomorphic Embedding Load Flow Technology (HELM™) method to provide deterministic load flow modeling for spacecraft power systems. Future deep-space vehicles need intelligent, fault-tolerant and autonomous control of power management and distribution. Due to communications latency, control algorithms for future autonomous space power systems need to be very robust, highly reliable and fault tolerant. Modeling of load flows is vital both ...

Technology Details: Holomorphic Embedded Load Flow for Autonomous Spacecraft Power Systems

Anticipated Benefits

Benefits to NASA funded missions

Potential NASA Commercial Applications: The project, when completed (all phases) will provide NASA with a reliable and fast State Estimator that will improve grid observability; optimization algorithms for load management under variable load demand and constrained capacity, yielding reliable results that have been power-flow checked; control-based applications; and auto-healing modules providing optimal (power-flow checked) action sequences for reconfiguration, in order to minimize brownouts and blackouts. These software applications provide the building blocks from which a truly autonomous po...

Benefits to the commercial space industry

Potential Non-NASA Commercial Applications: For non NASA opportunities, besides the existing AC grid applications, terrestrial opportunities are evident in AC, DC or AC-DC micro-grids. Terrestrial micro-grids pose unique scenarios for autonomous control because conditions differ substantially when the micro-grid is connected in parallel with the main grid instead of being islanded. Depending on the load/resource balance before islanding, quick actions will be required to ensure frequency and voltage stability. Renewable energy, particularly solar projects, will continue to play a larger role i...
