The impact of communications channels availability on distribution state estimator

This paper describes an advanced distribution management system controller and how a distribution network state estimator is formulated. The effect of communications channel availability on the distribution network state estimator under various types of communication systems is then analysed and discussed in details. From the distribution network state estimator, the accuracy of all network node voltages estimation against different communication system availability data with and without the consideration of communication channel redundancy are calculated and evaluated.
