Wide-Area Monitoring for Power Systems

In the United States, power interruptions cost the economy up to $135 billion each year. In 15 years from 1990 to 2005, power outages affecting over 100 MW or over 50,000 consumers have both more than doubled. A main cause, as revealed in the “Final Report on the 2003 Blackout”, is inadequate situational awareness. Importance of the situational awareness is further elevated by our sharply rising dependence and demand on electricity, the underway re-regulation of the electrical market, and the rapidly increasing deployment of distributed renewable power sources, all of which have resulted in a more complex and dynamic power system.

Enhancing the operator's real-time situational awareness necessary for safe and reliable grid operation, a wide area monitoring system (WAMS) is expected to maximally facilitate the understanding and management of the increasingly complex behavior exhibited by large power systems. At the heart of WAMS are phasor measurement units (PMUs), which deliver a level of data granularity that is many times finer than that provided by current measurement devices like remote terminal units (RTUs). When combined with time stamps from GPS satellites to form the synchrophasor data, the result is a picture of grid conditions that is truly real-time, every-where, and information-rich in nature.

Research at UW address challenges of the entire WAMS system at various levels, including:

  • More accurate and faster phasor and/or frequency estimation for PMUs;
  • Synchrophasor data analysis for power system monitoring applications such as event analysis, fault detection/localization, small-signal stability analysis and so on;
  • Quality-of-Service (QoS) ensured communications and networking system for WAMS;
  • Cyber-attack resilient design and user data privacy protection for WAMS
