Modeling and analysis of spacecraft power systems

A comprehensive large-scale power system modeling technique using the multiport coupling method is developed to facilitate design and analysis of present and future spacecraft power systems. The Boeing Computer Service's EASY5 program was used as the host software to meet various modeling and analysis needs for DC, small-signal, and large-signal analyses. Power subsystem or component model development from empirical data and reduced-order model generation using the complex curve-fitting technique are also introduced. A sample spacecraft power system, the simplified Direct Energy Transfer system, is modeled and its performance demonstrated.<
