Abstract

With the increasing integration of distributed generation, distribution grids are evolving from passive networks to active grids. The existence of DGs and energy storage devices makes the transient simulation of active distribution grids more meaningful compared with that of traditional distribution grids, but at the same time limits the simulation speed and system scale. This paper presents a passivity-guaranteed model order reduction method based on Krylov subspace theory for active distribution grids. Then simulations are performed using the IEEE 123-node test feeder, proving that the proposed method is feasible as a powerful tool in typical applications of the transient simulation of active distribution grids.
