2 To Achieve Operational Surety It takes a system that: Continually Monitors All Resources Energy, Water, Communications, Integrates Data From All Systems Building Energy Management, Generation, Storage, Systems, Communication Systems s Loads, Resources, and Utility Tie-Ins Enables Extended Continuity of Operations Monitors and Protects for Outages/Attacks The electric grid will become a grid of grids over the next 20 to 30 years with wide distribution of (renewable) energy resources and resulting microgrid technology It takes a Microgrid 2

3 Characteristics of a Smart, Secure, Microgrid Can disconnect from external grid and manage locally generated power Is selfsustainable for long periods Has distributed automated control and alerts Integrates renewable energy Smart, Secure Microgrid Can withstand cyber attack Real-time Integration to Create a System of Systems 3

4 Forces Driving Evolution of Systems Distribution networks are evolving to include distributed sub-systems and resources that require fast-acting local control (intermittent renewables, storage, EV s, and distribution automation) system technology is rapidly evolving as a result of computing power and data availability Stimulus funding, evolution of energy markets, and declining reliability are producing innovative solutions that complement/augment existing systems. Maturity of interoperability standards and customer demand for standards is resulting in vendor adoption Customer owned and operated generation is increasing Vulnerability to new/persistent threats physical and cyber

5 Evolution of Energy Systems Enterprise SCADA Master RTU/PLC 5

6 Evolution of Energy Systems Enterprise Enterprise : Forecasting load, renewable generation, price Optimization of Resources Automated Demand Response / Market Integration Resource Dispatch / Unit Commitment Advanced Analytics / Historian 6

7 Evolution of Energy Systems Enterprise : Localized / distributed control Manages a set of resources to a set of objectives (P &Q Import/Export) Can operate independent of Enterprise 7

8 Evolution of Energy Systems : Intelligently manages an asset Provides a plug-in interface for new assets Integration with Building Energy Management Systems Autonomous operation (limited) Capabilities beyond PLC s Enterprise 8

9 Evolution of Energy Systems Enterprise : Fault Location, Isolation, and Restoration at sub-system level Operates autonomously Real-time communication between nodes 9

10 Interoperability - Reducing the Cost of Integration, Upgrades, Expansion Optimization and Market I/F Enterprise Layer Resource Reliability and Stability Analysis Operations Service Bus (OSB) Area Area Area OSB OSB OSB Layer Layer Relays Breakers Reclosers Sync Check Interoperability Framework: Operations Service Bus provides the benefits of an Enterprise Service Bus, but in an ICS environment architecture provides maximum reliability, scalability, and performance Standards support allows devices and applications to be plugged-in Provides a vendor agnostic upgrade path QoS and Bandwidth management ensure high priority exchanges get through

11 Electric Grid Cybersecurity Risks (NIST) Greater communications complexity increases exposure to potential attackers and unintentional errors Networks linked to other networks may introduce common vulnerabilities spanning multiple domains More interconnections present increased opportunities for legacy and new cybersecurity attacks More network nodes means more entry points and vectors that potential adversaries might exploit Extensive data gathering and two-way information flows may broaden potential for compromises of data confidentiality and breaches of customer privacy

12 Defense in Depth Cybersecurity Model Model created by US National Security Agency (NSA) Balanced Best Practices strategy NISTIR 7628 guidelines support this model Should be integral to Smart Grid deployment platforms
