Brief Introduction to Smart Electric Grid, LLC

 

This startup company aims to provide power utilities and control centers a series of robust and reliable state monitors and the related solutions. Those new products are developed based on a revolutionary approach recently invented and patented at Smart Electric Grid, LLC. The new products include:


      1)Measurement Tuner
      2)Topology Estimator
      3)Smart State Estimator
      4)PMU State Estimator

     

    Measurement Tuner for Power System State Estimation


    Main feature:
    To improve the solving capability of Weighted Lease Square (WLS) state estimation by identifying and removing large disagreement among measurements including circuit breaker (CB) status.

     

    Large disagreement among measurement:


      1) Transmission line topology errors caused by wrong CB status measurements
      2) Bus merge errors and Bus split errors caused by wrong CB status measurements
      3) Parameter errors
      4) Measurement value errors
      5) Unsynchronized measurements

    Problems caused by large disagreement among measurements:

        1) Bias of the WLS state estimation solutions
        2) Unavailability of the system monitoring
