Next generation all-electric warships are featured with Integrated Power Systems (IPS) which, together with an associated Zonal Electric Distribution System (ZEDS), enable the integration of heterogeneous power sources, power distribution systems and loads into one single electrical platform to enhance Shipboard Power System (SPS) reliability and survivability. Along with the opportunities introduced by IPS systems, the inter-connectivity and complexity of the IPS represent a major system design and optimization challenge, calling for the development of effective analytical frameworks and numerical tools. This paper presents the University of Michigan’s recent effort to develop the methodology and tools to support the optimal power management of IPS. The Opal-RT real-time simulation system hardware configuration will be discussed, the SPS model will be described, issues pertinent to the multi-target real-time simulation will be highlighted, and approaches used to address those issues by leveraging the multi-rate characteristics will be elaborated on in the paper. In parallel to the real-time simulation, real-time optimization of the power management system has also been addressed. In particular, an algorithm is developed to explore the time scale separation of the IPS to improve the computation efficiency of the optimization. The results on the effectiveness of the algorithm will be presented in this paper through a numerical example.
