摘要：
The transient simulation of smart distribution grids extends the study category of traditional electromagnetic transient simulation, but at the same time limits the simulation speed and model scale. For this reason, a model order reduction (MOR) method is proposed based on Krylov subspace theory for large-scale linear distribution grids, which possess the features of linear system. Simulations are performed and lead to the conclusion that the model scale of smart distribution systems may be decreased effectively with appropriate MOR of the distribution grid, and then the simulation efficiency of overall smart distribution grids may be improved significantly.
