Development of a stochastic system model for an information embedded power system

This paper develops a model of an electrical power system, with its inherent embedded communication system, for the purpose of studying the characteristics of power system measurement errors due to communication delays. This model is referred to as an "information embedded power system" to emphasize the inclusion of information variables that represent measurements that have been delivered across the communication system and observed at a control center. These information variables are added to the standard power system model for the energy balance within the power system. A stochastic system model is developed, which is composed of both the physical infrastructure of the power system as well as the embedded computer network communication infrastructure. This type of analysis is an extension of traditional observability approaches, which usually only assume steady-state conditions in the power system and do not consider time delays in delivering measurements. An experimental platform has also been designed to validate the developed model.
