Parallel real-time simulation of Integrated Power System with multi-phase machines based on component partitioning

This paper presents a parallel algorithm for realtime simulation of the electromagnetic transient dynamics of the integrated power systems, which contains multi-phase machines and converters. The proposed algorithm is base on the component partitioning and Multiarea Thevenin Equivalent (MATE) methods. By partitioning the computational model of the multi-phase machine into several parts, a decomposition and coordination computation schema is designed. Moreover, with the help of the component partitioning, the overall system can be partitioned more flexibly and balanced, which helps to enhance the efficiency of the MATE methods eventually. Base on the proposed algorithm, a parallel simulation platform is constructed on a multi-core computer using OpenMP programs. Test results of a typical Integrated Power System (IPS) on ships verify the accuracy and efficiency of the proposed algorithm as well as prove the feasibility of applying the multi-core techniques to realize high performance power system simulations.
