2009-02 Power System State Estimation: Recent Trends and Future Needs
April 22-24, 2009


   Power system state estimation constitutes one of the critical functions that are executed at the control centers. Since a majority of the applications use the real-time data base provided by the state estimator, its optimal performance is of ultimate concern for the system operator, particulalry in nowadays deregulated and congested systems, where any decision has economic relevance. State estimators process the available measurements by taking into account the information about the network model and parameters. The quality of its results will therefore be dependent upon not only the measurements but also the assumed network model and its parameters. Hence, state estimators use various techniques to ensure validity of the results and to detect and identify sources of errors when the validity of results is questionable.

   This course introduces the basic statistical concepts which are used in formulating the power system state estimation problem. It illustrates the solution of this problem by well known methods which are customized to take advantage of the special structure of power networks and measurements. The concepts of network observability, identification of observable islands and their significance in system operation are explained. Importance of measurement design in maximizing the benefits and effectiveness of state estimators is discussed and illustrated via numerical examples.

   Synchronized phasor measurements which are rapidly populating substations worldwide are also being incorporated into the new generation of state estimators. The course will discuss their impact, benefits as well as the issues related to their proper placement in a given power system.

   Other relevant topics covered in the course are related with the extension of the state estimation concept to very specific scenarios. These include distribution networks, characterized by a very limited amount of real-time information, as well as huge regional networks, like the European interconnected system, which call for hierarchical approaches.

   Computer exercises will be used to illustrate the concepts and allow the attendees to interact with the course instructors during the hands-on part of the course.
