NYISO Wide Area Dynamic Measurement System Present and Future Developments
This presentation provides a brief description of the Wide Area Dynamic Measurement System that is being installed in the New York State by the NYISO and seven NY transmission owners. The key system components include Phasor Measurement Units (PMUs), Phasor Data Concentrators (PDCs), information, computers and telecommunication (ICT) system, and software applications.
The second part of the presentation will address lessons learned and further system development needs. Technical subjects will cover functional system architecture, PMU data quality, operator’s situational awareness, baselining strategies for dynamic system analysis, discovery of complex system events, dynamic model calibration and voltage stability monitoring enhancements.
Dejan J Sobajic, Ph.D., Consultant, has over 40 years of utility industry experience in the areas of SCADA/EMS design and real time system applications development; power system modeling, stability and control, and intelligent systems applications. Most recently at NYISO, he was responsible for the coordination of investment and demonstration projects proposed by New York State utilities in response to the 2009 American Recovery and Reinvestment Act.
In 1988 he pioneered the use of neural net technology in the field of power system engineering. Since 2005 he is the Chairman of the International Steering Committee for the International Workshop on Electric Power Control Centers.
