Power grids have risks that local accidents or sudden fluctuations in the power flow can cause large-scale blackouts due to a cascade of failures. For preventing such phenomena which are socially and economically undesired, it is significant to mathematically understand how power grids are tolerant to errors and attacks. Recently, the dynamical robustness analysis has been developed to argue robustness of networked systems by taking into consideration both network structure and system dynamics. In this study, we investigate the robustness of power grids in terms of the dynamical robustness of complex networks.
