Are utility-scale battery energy storage systems vulnerable to cyberattacks?

Utility-scale battery energy storage systems are vulnerable to cyberattacks. There is a lack of extensive review on the battery cybersecure design and operation. We review the state-of-the-art battery attack detection and mitigation methods. We overview methods to forecast system components behavior to detect an attack.

What is a battery energy storage system (BESS)?

Nowadays, the battery energy storage system (BESS) has become an important component of the electric grid . It can serve multiple services such as frequency regulation, voltage control, backup, black start, etc. .

Why is a battery energy storage system important?

Battery energy storage system (BESS) is an important component of a modern power system since it allows seamless integration of renewable energy sources (RES) into the grid. A BESS is vulnerable to various cyber threats that may influence its proper operation, which in turn impacts negatively the BESS and the electric grid.

What is data storage security?

Data storage security is maintained by applying the distributed architecture of blockchain . Blockchain provides authorized identity management to avoid the access of unauthorized users from sending commands and retrieving data.

How to prevent cyberattacks on electric grids?

In addition, cyberattacks on electric grids that can influence the work of the BESS have to be considered. We reviewed recent work in the field and concluded that blockchain and physical protection methods are the main approaches proposed to diminish the possibility of cyberattacks in the design stage.

Can a Bess framework provide cyber security for the electric grid?

Although in this paper, we consider cyber security from the BESS perspective assuming that the methods to provide cyber security for the electric grid are set by default, we overview the existing approaches in order to detect which of them might be adapted for implementation in the BESS framework.
