Discrete state simulation of power system dynamics

Conventional power system dynamic simulation is based on discretization of time. When distributed simulator is implemented, inherent continuity of time requires frequent communication among different solvers. Given the fact that state variables of system are usually loosely coupled, even independent, this paper introduces discrete state method into power system simulation, and presents how to imitate power system dynamics by discrete event simulation. The feasibility of the method is proved by a simple case. The potential advantages of the method are also summarized.
