Abstract

To accelerate the simulation of microgrid behavior, a parallel power system solver is being developed. The solver (CEMSolver) aims to accelerate the simulation of large-scale shipboard power system models created in MATLAB/Simulink with the SimPowerSystems blockset. While speedups of 50x have been reported, there remains insufficient confidence in the simulation results. This paper presents a point-by-point comparison of the results produced by MATLAB/Simulink 2012a and in parallel by CEMSolver. A large shipboard power system model is used for the comparison. It is concluded that, while the results show differences related to integration methods, all reported measurements of instantaneous voltage and current waveforms are within reasonable agreement.
