The Reality We Face….
“Blackouts will occur again in the future”
Our power grid is too complex to make it fail-safe!!

17. © 2015 General Electric Company - All rights reserved
So what is the Solution we seek.….?
Contain an Initiating event to prevent a Cascading, failure of
the grid!
And more importantly:
How to Restore power to customers ASAP!

A Modern EMS Control Center

19. © 2015 General Electric Company - All rights reserved
Today's Control Centers focus on:
Reliability, Security, Economics, Efficiency
Control Centers manage the
flow of energy in the grid:
• EMS manages the ‘physical flow’ of the higher
voltage ‘transmission’ system
• DMS manages the ‘physical flow’ of the lower
voltage ‘distribution’ system
• MMS manages the ‘financial flow’ amongst
electricity market participants

Three main EMS application areas
1. Supervisory Control and Data Acquisition (SCADA)
a. Monitor power system conditions in real time (every 2-4 sec)
b. Perform manual supervisory control actions
2. Generation Scheduling & Dispatch
a. System load forecast (SLF) & Reserve Monitoring
b. Generation/Interchange scheduling & Economic Dispatch
c. Real-time automatic generation control (AGC)
a. A Smart Grid Application since the ‘70s!
b. “Automatically ensure s that generation/load balance is maintained –
second by second”
3. Transmission Grid Management
a. State Estimation (SE)
b. Real time contingency analysis (CA) for N-1 system security monitoring
c. System Optimization:
a. Volt Var Control (VVC), Loss Minimization, Corrective controls
