Abstract :
This work presents an approach to parallelize the simulation of AC-Radial Shipboard Power Systems (SPSs) on multicore computers. Time domain simulations of SPSs are notoriously slow due to the order of SPSs and the presence of time-varying component models. A common approach to reduce simulation run-time is to partition power systems using Bergeron´s travelling-wave model and to simulate the subsystems on a distributed computer. In this work a SPS is partitioned along cable capacitor loops using a diakoptics-based approach and the simulation conducted on a quad-core computer. A case study is presented that empirically determines a good number of SPS partitions for a multithreaded simulation, such that the speed gain is maximal and accuracy is preserved.
