Abstract

The power grid needs to be frequently analyzed during the design process of power distribution network. Hence, an effective method being able to capture its transient behavior is desired for designers. This work utilizes macro modeling techniques, sparse recovery mechanisms, a proposed pseudo-node value estimation method, and an adaptive error control procedure to develop an efficient and reliable incremental power grid transient simulator. This incremental simulator not only can deal with adjusted values of the circuit elements but also can handle modified topologies of the design.
