On the Efficiency-Vs-Security Tradeoff in the Smart Grid
The smart grid is envisioned to significantly enhance the efficiency of energy consumption, by utilizing two-way communication channels between consumers and operators. For example, operators can opportunistically leverage the delay tolerance of energy demands in order to balance the energy load over time, and hence, reduce the total operational cost. This opportunity, however, comes with security threats, as the grid becomes more vulnerable to cyber-attacks. In this paper, the authors study the impact of such malicious cyber-attacks on the energy efficiency of the grid in a simplified setup.
