Advanced Energy Management System: Your solution to master renewable and digital transformation

The new EMS reference | Solutions for transmission | GE DigitalThe new EMS reference | Solutions for transmission | GE Digital

Digital transformation and rise of renewables

As utilities digitize their operations, their network assets need to be reliably mobilized to ensure energy transmission from multiple sources is maximized. High renewable energy penetration, intermittency and low inertia generate an increased level of threats. All of which requires a full understanding of real-time and future network status to enable a rapid response as changes occur.

 

GE’s Advanced EMS integrates the power of EMS, Renewables and WAMS  to enable operators to better operate, optimize and analyze while minimizing risk and increasing flexibility.

SCADA

Power systems monitoring increasingly involves managing millions of data points. These data points come from a variety of sources, at different times, each with their own resolution and quality. GE AEMS SCADA is fully prepared to receive data using traditional protocols, and more recent ones such as IEC 61850 and IEEE C37.118 (PMUs). SCADA collects all this information in real time to:

 

  • Process in terms of validity, usability, and accuracy, and store data for future analysis.
  • Combine into a flexible, simple, or complex calculation.
  • Provide operators and other control systems with flags and alarms, which are valuable for action and control.
  • Feed advanced applications such as network security and generation dispatch.

 

SCADA benefits:

 

  • Rapidly gain access to information and insight into any anomalies
  • Fast and automated power system actions under control of authorized operators
