A Collaborative Simulation Architecture for Influence Evaluation of Communication Network Faults on Power Grid System

With the rapid development of the smart grid, the power grid simulation integrated with its communication system becomes very important for power grid evaluation and deployment. In this paper, a collaborative simulation architecture for power grid system with the consideration of its communication system, in which the DIgSILENT, the QualNet, and an association controller are connected by two investigated interfaces, i.e., a data interaction interface (DII) and a dynamic control interface (DCI), is proposed for the influence evaluation of communication network faults on the power grid system. DII supports the information exchanging between the DIgSILENT and the QualNet, and the DCI is in charge of dynamical fault configuration of communication network, control message transmission from association controller to both DIgSILENT and QualNet, and state information feedback from DIgSILENT and QualNet to association controller. Experimental results show that the proposed interfaces can effectively implement data exchange between DIgSILENT, QualNet and association controller with an acceptable interface delay. And the influence of communication network faults on power grid system can be obtained obviously.
