Abstract :
The dynamics of micro-grid is of great complexity due to the diversity of DG and the highly nonlinearity within the system itself. Transient simulation tool plays a significant role to obtain a full and detailed response under various operation conditions. However, the simulation capability and speed are limited with the increasing size of the system. This paper presents a parallel algorithm for micro-grid transient simulation. It firstly decouples the solving of electrical system and control system using one step time-delay. Then an improvement algorithm on interface accuracy and numerical stability is proposed using explicit integration formula or interpolation formula. Finally, the control system is further decoupled according to its topology structure. The algorithms can be easily realized on a multi-core PC, and the computation load is balanced by DG modeling. The effectiveness of the proposed algorithms is validated in a benchmark low voltage micro-grid.
