Enhancing Resilience
A motivated, technically-sophisticated cyber attacker will inevitably penetrate a cyber-physical system despite robust security efforts.
LLNL researchers are developing algorithms that allow distributed energy resources (DER) — such as solar inverters and smart meters — to share input data with their neighbors and verify, for example, the voltages of different devices based on known data patterns to determine if they are normal. The underlying method uses "gossip" or update-and-share algorithms to propagate information about network communications from one component to another. Each device then mathematically verifies its neighbors' computations.
Managing DERs through collaborative autonomy also enables grid resilience to extreme weather events and climate change.
