Spacecraft power systems management, distribution, and design methodologies are reviewed, and prospects for achieving the high-efficiency goals required for future spacecraft power systems are presented. In particular, the methodology of solar array sizing and battery sizing is discussed, and the related mathematical equations are introduced. The growth in spacecraft energy requirements, which necessitate a large spacecraft power system to support the increased demands, resulted in on-going increases in weight, size, and cost of spacecraft systems. Therefore the power system management and distribution of such energy becomes an important factor in present spacecraft systems, affecting total spacecraft weight, size, and cost. This factor must be taken into consideration at the early design stages in order to meet the growing requirements for light-weight and low-cost spacecraft. Subject to certain technological advancements, spacecraft power systems can be reduced by 20 to 30% in size, weight, and cost without compromising mission requirements.
