Cluster Overview • Smart Grid vision for the wide area (primarily transmission) is: – Vastly more sensing at high, synchronous rates (example: PMUs) – New applications that use these data to improve • Reliability • Efficiency • Ability to integrate renewables • Security • Achieving the vision requires secure and reliable communications between sensors , control devices , and monitoring and control applications all owned and operated by the many entities that make up the grid | 3

Cluster Approach • What is the relationship between security (or lack of security) of communications for wide-area monitoring and control and the power-system’s behavior? • What kinds of hardware and software components will provide a secure foundation on which to build the wide-area monitoring and control infrastructure? | 4

Cluster Approach • Smart grid technologies bring new vulnerabilities along with benefits – Need improvements in security of wide-area technologies – Need ways to understand and mitigate the impacts of vulnerabilities • What cyber infrastructure designs will provide the integrity , confidentiality, availability , and real-time performance needed for wide-area smart grid operations | 5

Activity Highlights: Communication and Data Delivery • Functional Security Enhancements for Existing SCADA Systems – can machine learning applied to SCADA information flows and historical data reveal patterns to improve security? • GridStat Middleware Communication Framework: Management Security and Trust - robust key storage service, improved multi-cast authentication, and new trust assessment methods for power grid data dissemination • GridStat Middleware Communication Framework: Systematic Adaptation – instrumenting the data communication infrastructure to detect and respond to failures | 6

Activity Highlights: Applications • GridStat Middleware Communication Framework: Application Requirements - establishing cyber-physical standard test systems • PMU Enhanced Power System Operations - improving situational awareness by estimating system parameters and assessing stability in real time | 7

Activity Highlights: Component Technologies • Real-time Streaming Data Processing Engine for Embedded Systems - hardware support for Information Flow Monitoring to detect and mitigate attacks at hardware level • State-Aware Decentralized Database Systems for Smart Grid - collecting PMU data at one location isn’t practical. How can we split data among locations to enhance application performance, robustness, and availability? | 8

Activity Highlights: Component Technologies • Cryptographic Scalability in the Smart Grid - PKI for the Smart Grid requires scales orders of magnitude larger than previous PKI. Can it work? • Lossless Compression of Synchrophasor Measurement Unit Archives* - PMU data are highly correlated. How can that be exploited to save storage space? | 9

Cluster Impact • Influence from GridStat and previous CONES work on NASPI PMU data collection and dissemination architecture (NASPInet) • Patents filed: – Robust, distributed key storage with pro-active recovery – Systematic adaptation of data delivery • Grid Protection Alliance SIEGate product builds on CONES research | 10

Planned Research for Coming Year • Systematic adaptation of communications to power and cyber conditions • Crypto infrastructure scalability • Model-predictive control to choose control actions based on where the grid state is headed rather than just where it is • Physical impacts of cybersecurity events (expect testbed enhancements) • Securing processing nodes and storage nodes as well as the communications in the grid’s wide-area cyber infrastructure | 11
