This paper presents a software tool for automated management, supervision and control of shipboard Integrated Power Systems (IPS). A formalism of switched dynamic systems is used to develop a framework for optimal and supervisory control of the IPS. Switched dynamical systems are translated to mixed binary and real variable formulas which can be used to compute optimal control by dynamic programming or develop supervision strategies to preserve system integrity during disturbances. The tool consists of a simulation platform capable of representing continuous time differential algebraic power system models of varying fidelity, as well as discrete time events such as faults and reconfiguration. The simulation platform is integrated with symbolic computation tools for controller synthesis. Modular design allows for flexibility in incorporating multiple component and network models while faster than real time simulation speed enables efficient computation of controller strategies.
