This paper presents a comprehensive, large-signal, stability analysis of the solar array power system. The stability of the equilibrium points of a solar array system having a typical nonlinear load characteristic is analyzed. Employing state-plane analysis techniques, the dynamic behaviors of the system from an arbitrary initial condition are characterized and the region of the desired stable operation is identified. Furthermore, the stability and transient responses of the system operation near the solar array's maximum power point are evaluated. The dynamic responses of the spacecraft power system operating in the shunt mode and battery-discharge mode are analyzed. The analyses performed in this paper are also simulated. The solar array model was developed using the equations and parameter values in a Ref. and the EASY 5 program. Boeing-developed dynamic system analysis package program, was used to simulate the systems.
