Pre-Commercial Demonstration of a Direct Non-Iterative State Estimator

The conference paper that I presented at the 2018 IEEE PES T&D Expo in Denver has been published online, and I’m happy to share it here. This paper is related to the non-iterative state estimation method that I’ve worked on during my grad school and at my current job, so I did put a lot of time and effort for the method to get to this point. As usual, this paper is probably only interesting to those in the electric power industry, in particular to those who are interested in synchrophasor applications. Read below for the abstract and link to the full paper.

This paper discusses the development of a new hybrid state estimator (HSE) based on a Direct Non-Iterative State Estimation (DNSE). The DNSE method solves non-linear equations directly without iterations, which is fundamentally different from traditional iterative state estimation methods. A demonstration of the implemented DNSE system was carried out to validate the viability and performance of the method in processing live synchrophasor and SCADA data. The precommercial demonstration of the implemented DNSE was successfully conducted using live SCADA and synchrophasor data from the New York State power grid.
