Design and sizing of electrical power source for a nanosatellite using photovoltaic cells

The nanosatelitte that respects the standard form CubeSat present various engineering challenges due to its small size and surface area. The challenge is to incorporate a large amount of technology in a cubic form no bigger than 10cm3 and consumes only 1W. In this paper, we present the design and sizing of all components of electrical power source (EPS) such as photovoltaic solar cells specifications based on a new strategy of calculation by scenario, secondary power sources specifications presented by the batteries, and power control distribution unit (PCDU). Also the simulation results for the management of the power system in the nanosatellite are displayed.
