  2. Tomorrow’s Power System Managing Future Power System Complexity will Require a New Grid Operating System

  3. Drivers for the New Generation EMS • Tectonic Changes in the Electricity Grid • The power system is revolutionizing at an exponential pace into a highly interconnected, complex, and interactive network of power systems, telecommunications, the Internet, and electronic commerce applications • Drivers of Change • Variable Generation • Demand Response • Electric Vehicles • Smart Meters • Distributed Generation • PMUs • Communications

  5. Why is the New Generation EMSgoing to be fundamentally different? • More Real Time data • Phasor Measurements • Data from distribution (DG, DR, EV, MG, etc.) • Faster Communications – Larger Volumes • Intelligent Substations • Distributed Database Architecture is Different

  6. Proposed Communications

  7. PMU Communications

  8. Each Application – Different Data • Monitoring at the control center • Needs all data points • But at slow rates (every few seconds) • Special Protection Schemes • Needs few data points • But at fast rates (many times a second) • Each application must access this data in a different way • Moving real time data from source to application is a complex optimization task

  9. Data Base Issues • Real time data base must be distributed • Large amounts of calculated data must be part of this data base • Static data base must be distributed • Historical data base will require still another design • Substation data bases and system level data bases have to be coordinated • All data bases in the same interconnection will have to be coordinated • Standards will be key

  10. Potential New Applications • Distributed vs Centralized • More calculations done at substations (e.g. Distributed State Estimator) • Automatic vs Manual • Closing the loop (e.g. Oscillation Detection vs Oscillation Control) • Wide-area control/protection (e.g. more SPS, more FACTS control) • Model based control (e.g. SE based SCOPF)

  11. Where are we on this path? • PMU deployment and Substation Automation • Distribution Automation (including smart meters and smart customers) • ARRA Projects a big boost ($9B) • New Applications lagging • Need more interconnection-wide coordination • Need Utility-Vendor Partnerships
