With the increase of global malicious activities, it is particularly necessary to optimize the allocation of limited urban protective resources and protect power network from malicious attacks. There is plenty of research on evaluating the risks of malicious attacks on electricity network, however, conventional risk-based approach does not take strategic adjustment of malicious into account, nor can it determine the optimal allocation of global protective resources. In this paper, an optimal allocation of protective resources based on game theory was proposed, which combined game theory with risk assessment, taking full account of strategic interaction between defender and attacker. IEEE 30-bus network was taken as an example to verify the applicability and reliability of the method, so as to confirm the advantages of the method in determining the global optimal allocation of protective resources.

The gut microbiome plays many crucial roles in the maintenance of immune homeostasis. Alteration of the gut microbiome and metabolites has been shown to impact vaccine efficacy.
