The conventional centralized electric grid architecture that dominated in the 20th century can no longer keep up with the technological advancements being made in the present world. This energy infrastructure network, referred to as a smart grid, is drawing attention for its safe and smooth functioning. For the successful functioning of a smart city the energy infrastructure must also integrate information and communication technology appropriately. Smart cities can be defined as cities that incorporate information and communication technology in order to provide benefits such as efficiency, reduced cost, convenience and higher quality of life.
In the end, we have presented a case study of FDI attack detection using machine learning technique on IEEE 9-bus and 14-bus system. We have performed experiment for Distributed Denial of Service (DDoS) and False Data Injection attack (FDI) to validate our framework effectiveness and established the efficacy of proposed model. Our work addresses the pre and post attack scenario, attack vector formulation through hierarchical PetriNet modeling and recovery mechanism. Through this paper, we propose a novel Cyber Physical Defense Framework (CPDF) based on National Institute of Standards and Technology (NIST) guidelines to address the cyber attack on SG. Many researchers have analyze the different stages of cyber-physical co-ordinated attacks like attack detection, prevention, impact analysis and recovery plans but there exist a research gap to address all the issues under single framework. Being capable of performing such sophisticated operation it also bears the vulnerability of being exposed for cyber-physical co-ordinated attack that may lead to catastrophic effect. As a backbone of C.I., Smart Grid demonstrates ability to precisely monitor large scale energy systems and designed in order to achieve complex local and global objectives. These close conjunctions of sensors with communication infrastructure intrinsically linking to society’s Critical Infrastructures (C.I.) are being witnessed more often in the context of Smart Grid (SG). 3Norwegian University of Science and Technology, Gjøvik, NorwayĬyber-Physical Systems (CPS) is the amalgamation of highly sophisticated sensors with physical spaces.2Indian Institute of Information Technology, Allahabad, Allahabad, India.1Indian Institute of Information Technology, Allahabad, Prayagraj, India.Ayush Sinha 1* Manasi Mohandas 2 Pankaj Pandey 3 O.
