Trade-off analysis of low earth orbit spacecraft power supply system by Genetic algorithm

The spacecraft electrical power system design process is a very complex task; it depends on multiple issues, which will have a great effect on the trade-off analysis of designing Spacecraft Electrical Power System. It should also meet various design objectives under certain constraints. The main goal of designing the spacecraft power supply system is to reach the optimal solution of selecting the optimal available technologies and its components, like the type of solar cells, the configuration of the solar arrays, technology of batteries, and bus voltages. This paper discusses important issue such as automation, intelligent design and trade-off processes of the Spacecraft Electrical Power System implemented by the practical design processes using GENETIC ALGORITHM. The new method reflects that simulation and optimization techniques can be effectively used for improving and automating the designing method. Multi-objective of optimal design solutions unnaturally evolved in the result of the interfacing with Genetic algorithm techniques with system sizing or examination tools under the supervision of the practical constraints. Compared the standard optimization techniques, a multi-objective layout approach provides a clear understanding of the impact of their layout selections on the given layout variables at the same time.
