Abstract Details

2018, Master of Engineering, Case Western Reserve University, EECS - System and Control Engineering.
Managing the solar PV power generation, battery charging and discharging cycles, and load scheduling onboard a spacecraft is an essential task of space travel. This process is currently managed by mission control on earth, as most manned space flight take place in lower earth orbit. In deep space travel, however, the communication delay and bandwidth limitations between the space vehicle and the earth can be a significant constraint. This requires autonomous power management onboard the spacecraft without engaging mission control on earth. This research project uses Mixed Integer Programming (MIP) to solve the electric generation and load scheduling problem onboard spacecrafts during deep space missions. The problem formulation is required to be reliable and robust, and the solution performance (MIP gap and time convergence) will also need to be good. In this project, a hypothetical spacecraft has been modeled. Using the CPLEX solver via the AIMMS modeling platform, we create a program that manages the electrical loads onboard the spacecraft over a 24-hour study period with 10-minute scheduling intervals. With over 8,000 decision variables (including both continuous and integer types), the program converges to an optimal solution with outstanding performance. This project has been sponsored by the Power Division at NASA Glenn Research Center in Cleveland, Ohio.
