GEN-SE® Generalized State Estimation

GEN-SE® is the leader in state estimation software, deployed in over 120 control centers around the world. It is a critical component of energy management systems (EMS) delivered by Nexant's global partners.

GEN-SE is also offered as a standalone software which can interface with your current EMS to support the tuning and cleansing of "bad data." GEN-SE's advanced features for detecting bad parameters, bad telemetry, and inconsistent models are cost-saving tools for operation engineers faced with recurrent poor state estimation results. Good state estimation results are now the key to proper situation awareness, as most advanced security analysis software relies on these results to provide key indicators on reliability status.

For ISOs relying on state estimation to compute nodal electricity prices, GEN-SE can ensure that erroneous data is excluded from day-ahead and real-time market calculations.

GEN-SE implements powerful orthogonal transformations. Unlike other estimators, it estimates a system's state, topology, and network impedances to construct the statistically best model needed for online monitoring and optimization functions.

It routinely solves (within seconds) some of the world's largest and most complex state estimation problems.

GEN-SE's features include:

• Fast orthogonal transformations for highest computational reliability
• Selective modeling of the network at bus-section and breaker level
• Radical improvements in bad data, including advanced techniques for topology error detection
• Parameter estimation, fully interacting with state and status estimation
• Accurate modeling of power system devices, including local controls and limits
• External networks with mixed telemetered and pseudo-injection data
• Modern software architecture for easy interfacing and upgrading
• Great flexibility, facilitating substation-by-substation commissioning and maintenance
• Sophisticated localization techniques for high computing speed on systems of any size
