Recently, there are growing concerns about smart grid security and resilience. The performance of smart grid may suffer from component failures or targeted attacks. A sophisticated adversary may target critical components in a smart grid, leading to cascading failures and large blackouts. To address this critical issue, this paper begins with identifying the most critical components that lead to cascading failures in the smart grid and then presents a defensive mechanism using energy storage to defend against cascading failures. Based on the optimal power flow control on the standard IEEE power system test cases, we systematically assess the component criticality and simulate attacks against power grid components and evaluate the consequences. We also carry out extensive simulations to investigate the effectiveness of deploying Energy Storage Devices (ESS) in terms of storage capacity and deployment locations to mitigate cascading failures. Through extensive simulations, our data shows that integrating energy storage device into the smart grid can efficiently mitigate cascading failures.
