Simulation, estimation, analysis, and control of spacecraft power systems

The authors present a steady-state security analysis and simulation of spacecraft power systems. A power flow simulates systems measurements for a given operating condition. A state estimator uses these measurements to estimate the state of the system. Using the results of the state estimator as the base case solution, a contingency analysis is performed to determine the system security for a given set of contingencies. Corrective control is applied to alleviate any problems found in the contingency analysis. The algorithm applies to either a single-phase system or the positive-per-phase equivalent of a three-phase system
