Transcript

  • 1. Applying ISI Capabilities to Energy Challenges
    Gordon Roesler
    ISI Directors’ Offsite
    12-13 January 2010
  • 2. The Century of Scarcity

    Food
    Water
    Environment Energy
  • 3. ISI’s Strengths Fit a Gap in Energy Research
    “Supersystems”, system-of-systems
    Physical models of very complex distribution system, i.e. “the grid” (smart or not)
    Machine learning/artificial intelligence for improved real-time control
    Communications network(s) interwoven with physical network
    Fault-tolerant real-time computing
    Decision support and system engineering
    Data mining
    Pre-deployment: complex decision space
    Post-deployment: operator support, visualization, pattern recognition

  • 4. Grid reliability: a deep intellectual challenge
    2003: Local conditions cascaded to blackout
    50 million customers dropped
    61.8 GW power tripped off
    Economic cost $4-10B
    General causes
    Cascading line tripping by dynamic line loading
    often leads to unsuccessful line restoration attempts
    Cascading equipment tripping by overexcitation
    Loss of synchronism due to angle instability
    Oscillatory instability causing self-exciting inter-area oscillations
    Exceeding allowed frequency range (over and under frequency) due to imbalance in active power between generation and load
    Voltage instability / collapse

  • 5. ISI Opportunities to Enhance Grid Reliability
    2003 Outage Task Force selected recommendations
    “prudent expenditures for…reliability (including investments in new technologies)”
    “DoE should expand…research programs on reliability-related tools and technologies”
    “Improve…training and certification”
    “Better real-time tools for operators and reliability coordinators”
    “Improve quality of system modeling data”
    “Require use of time-synchronized data recorders”
    “Clarify criteria for identification of operationally critical facilities”
    “Develop corporate-level IT security governance and strategies”
    “Improve IT forensic and diagnostic capabilities”

  • 6. Phasor measurement units: the holy grail?
    40 PMUs installed as of 2005
    SCE installing 70 more over next 18 months (goal: one at each substation)
    Objective: perfect knowledge of phases  linear transform to determine loads and sources
    Too few PMUs  under-determined problem
    Algorithms for real-time control not developed
    6
    line
    GPS
    As of
    2005
    ISI’s capabilities in data mining, modeling, and artificial intelligence could advance PMU use for real-time control
  • 7. Human issues related to grid reliability
    Operators were ineffective at all stages of 2003 blackout
    Inadequate visibility into long-range state
    Displays and indications confusing
    Inadequate training and simulation
    Increase in automation to date at grid control centers has increased operator overload
    Need to distil information
    Build machine learning into warning systems
    50% of transmission & distribution workforce is eligible for retirement NOW
    Knowledge capture
    Training of new work force
    Automated backups

  • 8. Opportunities in discussion with potential sponsors
    Grid reliability
    Utility discussions, may grow to regional alliance
    Disaster planning and recovery
    Possible partnership with CalTech (earthquake warning)
    Possible role in contingency planning for wave demo site
    Renewables
    Congressional (wave energy)
    Buoyant energy storage (with U. Hawaii, conceptual)
    Analyze impact on grid stability
    Workforce training, operator assistance
    Utility discussions
