1 Data Fusion & Multi-Sensors in Power Grids Rabinder N. Madan FIEEE Program Manager, Systems Theory Office of Naval Research

2  Measuring Devices: From Analog to Digital Remote Terminal Unit (RTU) Intelligent Electronic Device (IED) Smarter Grid! Safer Grid? Analog Power Meter Smart Meter  Data Collection: From Human to Computer Networking Higher precision Real-time monitoring Dynamic scheduling Less human resources The Potential Threats?  Computer security: bad data injection, network hijack …  Communications reliability: error rate, communications delay …  Customer privacy: data eavesdropping, identity disguise …

3  Robust System Structure Design  Inter-Operability  Multiple Level Interface  Data Encryption and Aggregation  Asymmetric Key System  Small Time Scale Data Aggregation  Digital Signature Authentication  Cyber Attack Detection and Correction  Meter Redundancy Arrangement  Detectability Analysis  Bad Data Processing Safety Solutions
