Computer Architecture and Multi Time-Scale Implementations for Smart Grid in a Room Simulator

Abstract

This paper describes how to utilize physics-based unified modeling of complex electric power systems in order to design a multi-layered interactive Smart Grid in a Room Simulator (SGRS). In this simulator, the dynamic response of a given interconnected grid is simulated and assessed as a family of interfaced sub-processes jointly evolving at different timescales. Compared to state-of-the-art simulators, advantages of the SGRS are that it is scalable to large systems since it uses distributed computing and that it allows for privacy of different components since one object does not need to know the models or methods of another object. Standardized and transportable objects representing physical components at various degrees of temporal, spatial, and functional granularity are constructed by different users and added to the SGRS platform for future use by all. This allows users to simulate and assess the effect of the technology of interest to them, which makes the SGRS effective in supporting the deployment of new technologies with wellunderstood effects. Examples on the SRGS are described for simulating market-driven sub-processes and the fast dynamics sub-processes in response to market actions and/or to sudden hard-to-predict disturbances.Keywords-Cyber Physical Systems (CPS) for energy systems; computer platforms; distributed simulations; event-driven simulations ; simulations-based smart grid test beds.

Toward a Unified Modeling and Control for Sustainable and Resilient Electric Energy System

“…While these theoretical formalizations are beyond the objectives of our paper, we do illustrate the use of transformed state space for scalable modeling, control and simulations in the domain application of electric energy systems. The simulation platform for our Smart Grid in a Room Simulator (SGRS) utilizes the proposed modeling framework and can be used by the broader community to demonstrate concepts described in this paper (Wagner et al, 2015).…”

“…These standards and protocols define information that should be exchanged in the next generation SCADA for the electricity services to be provided at value. The proposed unified multilayered modeling has been used to design a computer platform for scalable simulation of smart grids named Smart Grid in a Room Simulator (SGRS) (Wagner et al, 2015). As such it sets the basis for simulating electricity markets, and their effects on physical system response.…”
