摘要
Abstract
The microgrid containing a large amount of high frequency power switches puts forward high requirements for the real-time simulation of hardware-in-the-loop of power system. In order to reduce the storage pressure of inverse ma-trix algorithm,the whole network is divided into multiple subnetworks,and only the parameters for computing input and internal state variables of subnetworks are stored. A general principle to choose input variables and formulate net-work equation is proposed and the generation method for undirected graph of network equation is studied. In order to limit iterative calculation to the local network,the state variables are used as the input variables at sub-network port. A numerical example shows that the multiport-hybrid-equivalence-based network tearing technique gives consideration to alleviating on-chip memory requirements and reducing the computational burden,and a low-voltage microgrid is simu-lated in a real-time simulator with 5μs time-step based on FPGA.关键词
