2. Today’s Overview

3. The Opportunity Situational Awareness/Military Readiness • DoD’s objective is to have the most reliable source of energy possible, especially to support critical operational capabilities. • Looking for the most cost effective solutions to meet their objectives while operating within the constraints levied on the Department. • New technologies capable of providing monitoring and fault detection prior to failure – providing a predictive tool set to enhance maintenance and support capabilities. The cost of energy is contained in the Operations and Maintenance (O&M) account.

4. Smart Grid Aspects Energy Source Bulk Power Distribution Energy Storage Power Grid Reliability Energy Facilities Central Station Generation Renewable Energy Power grid reliability impacts all aspects What are the key components? What are the costs drivers? What are the long term prospects? What actions can be taken to reduce costs while not compromising services?

5. Operations and Maintenance Programmatic Support – 70/30 Rule Smart Grid is a modernization of the electricity delivery system so that it monitors, protects, and automatically optimizes the operation of its interconnected elements – from the central and distributed generator through the high-voltage transmission network and the distribution system, to industrial users and building automation systems, to energy storage installations, and to end-use consumers and their thermostats, electric vehicles, appliances, and other household devices.

6. Benefits of the Smart Grid Provides Power Quality for the Digital Economy. The Smart Grid provides reliable power that is relatively interruption-free. Optimizes Asset Utilization and Operational Efficiently. The Smart Grid optimizes assets and operates efficiently. Anticipates and Responds to System Disturbances (Self-heal). The Smart Grid independently identifies and reacts to system disturbances and performs mitigation efforts to correct them. Operates Resiliently against Attack and Natural Disaster. The Smart Grid resists attacks on both the physical infrastructure (substations, poles, transformers, etc.) and the cyber-structure (markets, systems, software, communications).

7. Benefits of the Smart Grid (Continued) Allows Direct Participation by Consumers. The smart grid consumer is informed, modifying the way they use and purchase electricity. They have choices, incentives, and disincentives. Accommodates all Generation and Storage Options. The Smart Grid accommodates all generation and storage options. Enables New Products, Services, and Markets. The Smart Grid enables a market system that provides cost-benefit tradeoffs to consumers by creating opportunities to bid for competing services.

8. An Innovative Technology • Distribution Fault Anticipation (DFA) • System utilizing digital signal processing methods to extract feature vectors (electrical signatures), in conjunction with pattern-matching technologies to report specific anticipated and current failure modes. • Continuously monitors distribution feeders using intelligent automated algorithms to detect, characterize, and predict failures or faults in electrical power. • Enables advanced situational awareness and decision processes to improve reliability by detecting, alerting, and enabling repairsbefore equipment failures and outages occur. • Works autonomously without the need for personnel to spend time analyzing waveforms.

Measuring fault current at substation and putting it in feeder model reduces search area to sections Recognizing recloser shown in red. characteristics and putting them in model further reduces search to two circled areas (still based on substation measurements only). DFA detects failures and incipient failures in order to locate them for proactive Distributed measurements corrective actions. further reduce search to single area.
