A Multi-domain Co-Simulator for Smart Grid: Modeling Interactions in Power, Control and Communications.

摘要

Smart grid studies have been generating a lot of interest both in the business and research community as it is now seen as the future power grid. However, understanding the interactions amongst different components that form the smart grid is a Herculean task. Researchers rely on simulations as one of the means of understanding the effects of coupling the distributed control systems, communication networks and power system to form the smart grid, but synchronization of the simulation times of the various simulators, and data exchange amongst the different components are challenges that must be overcome. Fixed-time-step and queuing system synchronization schemes have been proposed, but the fixed-time-step synchronization scheme suffers from accumulation errors and the proposed queuing method does not scale well. In this thesis, we present a synchronization scheme that eliminates accumulated synchronization errors, and efficient data exchange scheme which enhances the scalability of the platform.
