摘要：Due to close coupling between physical and information systems, an unexpected attack on the node of the information system will result in great operational risk of global energy interconnection. A defensive resource allocation strategy for cyber-physical systems is proposed. Various risk factors of information systems are quantitatively evaluated in this paper. An optimal defensive resource allocation model is built to strengthen the security and stability of the cyber-physical systems, which accounts for nodal vulnerability and nodal risk degree. Simulations results of a test power system and its corresponding communication networks verify the effectiveness of the proposed allocation strategy.
