This paper describes the FNCS framework that uses a federated approach for integrating power grid and communication network simulators. Compared to existing approaches, FNCS allows co-simulation of both transmission and distribution level power grid simulators with the communication network simulator. To reduce the performance overhead of time synchronization, FNCS utilizes optimistic synchronization strategies that make speculative decisions about when the simulators are going to exchange messages. GridLAB-D (a distribution simulator), PowerFlow (a transmission simulator), and ns-3 (a telecommunication simulator) are integrated using the framework to illustrate the enhanced performance provided by speculative execution on a smart grid application. Our speculative execution approach achieved on average 20% improvement over the existing synchronization methods.
