Resilience enhancement strategy for cyber–physical distribution systems that considers cross‐space propagation of information risk

Cyber–physical distribution systems with renewable energy should have high resilience under extreme conditions. However, in a system deep cyber–physical coupling, the propagation of information risk impairs system. This paper proposes strategy to improve that considers cross-space risk. First, mechanism for interaction between cyber space and physical is analyzed, an model proposed. Second, status key device nodes quantified according model, optimization control obtained, whose objective function minimum coupling network. Third, fault restoration Finally, reports experiments using modified IEEE 33-node 123-node networks simulate proposed verify its effectiveness.
