enhanced Linear State Estimator

eLSE is a software for obtaining the best estimate of the real time state of the power system utilizing only synchrophasor data. It provides a linear solution of the state estimation problem with synchrophasor measurements. Compared to the traditional state estimator, eLSE always solves, and is much faster and highly accurate.

Use Cases of eLSE

Provide the real time state of the system

eLSE calculates complex bus voltages at each bus using PMU measurements.

Key Features

  • Real Time System Model and Input to Downstream Applications

  • eLSE can provide real time system model and serves as an input to the downstream applications like contingency analysis, remedial action scheme, AGC/AVC, Energy Markets, Oscillation Detection, Dynamic security /Voltage stability Assessment
  • Capability to Model Power System Equipment

  • eLSE has the capability to model series capacitors, shunt capacitors, reactors, bypass breaker, split bus
  • Interface for accepting Breaker Status

  • eLSE has an interface to accept Breaker status using Inter-Control Center Communications Protocol (ICCP). It can also obtain breaker status information from PMU digitals

About EPG

Electric Power Group, LLC (EPG) has been pioneering the development and deployment of synchro-phasor technologies since 2000. Our principals have extensive experience in running and managing utility grids, investigating root causes of major blackouts (WECC 1996, EI 2003), and leveraging this deep domain knowledge to develop industry leading synchrophasor technology applications for wide area real time monitoring, visualization and situational awareness.

The EPG team has extensive hands-on experience with synchrophasor standards, networks, system architecture, deployments and performance analysis through work at EPG for leading ISO's and utilities including PJM, NYISO, ERCOT, CAISO, MISO, BPA, TVA, SCE, AEP, LADWP, SRP, Duke, Dominion, NYPA and other companies.
