Case Study: The Challenges of Distribution System State Estimation

Presented by: Jens Schoene and Muhammad Humayun

Part 1 in 2 Part Series: Leveraging Sensors for Greater Situational Awareness


To provide a real world example of a problem solution approach for improving Distribution System State Estimation (DSSE) for ADMS applications.


  1. Current status of DSSE
  2. Limitations of current modeling schemes
  3. Identification of improvements that can be achieved by properly locating sensors and defining the key data acquisition requirements
  4. Development of a Sensor Strategy Plan

Learning Goals:

  1. Understanding the limitations of current approaches
  2. How to define requirements for sensors including optimal location, type and information requirements
  3. Creating of a standard approach for sensor deployment.
