Background of Our Novel State Estimators
A developmental software company with methods to revolutionize the monitoring of the electric smart grids
In March 2020, North American Electric Reliability Corporation (NERC) published a survey about the reasons of the loss of Energy Management System (EMS) system, a system of computer-aided tools used by system operators to monitor, control, and optimize the performance of generation and/or transmission systems. The survey shows that 45% of loss of EMS is caused by the divergence of state estimator.
State estimator is the most important function in EMS. The purpose of state estimator is to provide a consistent base case for use by other network applications such as Power Flow and Contingency Analysis. State estimator can be considered as the "heart" of EMS.
Our Non-Divergent State Estimator (NDSE) aims to solve the problem of loss of state estimator. The voltage solution obtained by NDSE only depends on the measurements, system topology and paramaters, without human involvement or adjustment or any forms of linearization or approximation.
