Abstract:The futuristic smart grid require creative architectures for Information and Communication technologies (ICT) networks. One such architecture must need some sort of topological control for the next generation grid. To assess architectural impact and effectiveness, simulation models are important. Communication networks are expected to be tightly coupled-integrated element for smart grid systems. The co-existence of communication and control and their joint operation necessitate accurate modeling of communication events. While at the first glance, it is tempting to model the communication network as a black box that introduces delay/s between its input and output, the complex interactions among grid network and its components and between data sources and the network make it less tractable. The paper focuses a software-based smart grid architecture modeling using an OMNET++, a discrete event simulator. It consists of layers of independent management modules for communication, and control events that represent real-world cases using generators, circuit breakers, switches or relays, transmission lines and loads. A topology sorting algorithm is presented using modified Dijkstra‟s Algorithm, and several contingency scenarios for an IEEE 14 bus system was carried out emulating real electric test-bed conditions.
