Cybersecurity for Battery Energy Storage Systems
Abstract: Grid-scale battery energy storage systems (BESSs) are being connected to the power grid to help with grid services and increasing power demands. BESSs contain stacks of battery cells that are controlled and managed by battery management systems (BMSs). Some critical functions of BMSs are sensing, estimating battery states like the state of charge (SoC), and balancing cells; BMS sensors are susceptible to cyberattacks like false data injection attacks (FDIAs) which can be used to corrupt SoC estimation, and could result in thermal runaway events. As part of a defense in depth cybersecurity approach for BESSs, cyberattack detection methods are needed within BMSs to monitor for cyber intrusions. In this talk, a three-pronged method combining battery modeling, estimating, and a recursive summation algorithm is used to detect FDIAs targeting battery voltage sensors. The method consistently exhibits accurate FDIA detection with false positive rates as low as 0%.
Speaker: Victoria O’Brien is a Senior Member of Technical Staff in the Electric Grid Security and Communications Department at Sandia National Laboratories. She obtained a B.S., M.S., and Ph.D. in electrical engineering from Texas Tech University in 2020, 2021, and 2023, respectively. Her research interests include the cybersecurity of battery energy storage systems, control systems, and the smart grid. Dr. O’Brien was the recipient of the Graduate Assistance in Areas of National Need (GAANN) Fellowship (Texas Tech University) in 2020, Advanced Energy Conference (AEC) “Best Poster” Award in 2021, and Power and Energy Conference at Illinois (PECI) “Best Paper” Award in 2022.
