A novel approach of interdependency modeling of Smart Grid and Supervisory Control and Data Acquisition (SCADA) networks is introduced. Methodological approach for vulnerability reduction considering both structural and functional vulnerability is introduced in this paper. The analysis of cyber-attacks on Smart Grid and SCADA network is discussed. Paper discusses importance and need of clean, sustainable and green energy for the future. Paper also analyzes interdependent Smart Grid and SCADA network under severe emergency situations. The contribution of this paper provides novel network with integrated infrastructures for active and survivable network operation. Thus novel Smart Grid and SCADA interdependency network will act as future's clean, sustainable and Green energy model.
