Secure smart contract-enabled control of battery energy storage systems against cyber-attacks

Battery Energy Storage Systems (BESSs) are an integral part of a sustainable and resilient smart grid. The security of such critical cyber-physical infrastructure is considered as a major priority for both industry and academia. In this paper, we propose a new distributed smart-contract based control approach of BESSs to enable collaborative and secure operations among them. We present a comprehensive discussion on how control strategies can be implemented as smart contracts and deployed on a distributed network of BESSs nodes in order to operate these storage systems according to secure consensus. To verify the effectiveness of the proposed method, we analyze the vulnerabilities of BESSs when controlled according to traditional schemes vs. smart-contract enabled control. Simulation results show that if individual BESSs achieve a certain maximum threshold of exploitability, then the network of distributed BESSs is more robust to cyber-attacks in smart contract-defined control.
