    Strategies to Improve Control & Stability of the Bulk Power System FACTS, HVDC and Wide-Area Monitoring, Protection and Control

    Le Tang, ABB

    May 30, 2013

  • Bulk power system control objectives

    System stability

    Load balancing

    Frequency and voltage control

    Security

    Continuity of service under disturbance, equipment outages

    Economy

    Economic utilization of resources, efficient market

    Sustainability

    Maximum utilization of renewable energy

    Cyber-physical security

    Resilience to cyber-physical attacks, intrusion prevention

    detection, self defense

  • Requirements for effective control Situational awareness Knowing whats going on

    Sensing technology/Communication technology

    Data analytics/ Information presentation technology

    Decision technology Able to find the control strategy to get the best results fast

    Forecasting

    Control and optimization

    Threat detection and mitigation

    System modeling, performance prediction, and faster than real time simulation

    Controllable equipment have the means to effect change (often ignored)

    Able to change power flow pattern

    Able to shift power over time

    Able to integrate renewable supplies and consumer productions

    Able to modulate supply and demand at high speed

  • Enabling technologies Real time SCADA

    PMU, WAMS, and WAMAPC

    IT and OT integration and big data handling

    Power Electronics based Actuators

    FACTS, HVDC, and other VSC based applications

    Power flow control, stability control, voltage support, oscillation control,

    loss reduction

    Demand response

    Demand side management

    Time of use pricing/ Real time pricing

    Energy storage

    BESS, CAES, Flywheel ES, SMES,TESS,,

    Smart Grids call for new control & protection paradigms

    Future:

    Multi-terminal links

    Multi-taps (power highway exits)

    Evolving from point-to-point

    towards overlay DC grids

    Mixed AC / DC grids

  • WAMS: A huge improvement potential for control with needed actuators (FACTS, HVDC etc.) Market scenario

    ABB Group May 31, 2013 | Slide 7

    Demand for WAMS

    Traditional Grids Good monitoring already existed Centralized power generation One-directional power flow Generation follows load Operation based on historical

    experience Limited grid accessibility for new

    producers

    Industry Challenges Need for more electricity Emissions reduction Renewable energy Optimal use of ageing assets Ensure reliability of supply Energy efficiency and security

    Future Grids Decentralized and distributed power

    generation Intermittent renewable power generation Consumers become also producers Multi-directional power flow Load adapted to production Operation based more on real-time data FACTS (SVC, TCSC, etc.), HVDC
