OpenAGC

OpenAGC is an open systems-based automatic generation control package ideal for utilities in need of replacing their SCADA/EMS-based AGC, companies needing a more robust AGC/Generation Dispatch system, or companies requiring a backup AGC system for an emergency control center.
OpenAGC is a state-of-the-art generation control and dispatch system comprised of the following components:

• Load Frequency Control
  
• Economic Dispatch
  
• Reserve Monitoring
  
• Production Costing
  
• Emissions Dispatch
  
• NERC Performance Monitoring

OpenAGC is highly tunable to allow for optimum control area performance and control response. Non-linear filtering of Area Control Error (ACE) and Unit Control Error (UCE) are used to provide realistic system response.
Unit operating modes supported include: off-line, standby, manual, base-load, econ, ramp, and auto. Each unit can be included in the ACE regulation based on the following regulation modes: non-regulating, regulation, emergency assist, regulation/emergency assist. Automatic time error and inadvertent interchange accounting and correction are also supported. NERC performance monitoring (CPS1, CPS2) reports are generated and historically archived.
Reserve monitoring is performed for two time periods, short-term and long-term. Spinning and standby reserves are computed and any deficiencies are alarmed.
Economic dispatch supports multiple Incremental Heat Rate curves, multiple fuels, and fuel costs. Three sets of economic basepoints are calculated: real-time, study, and optimal.

Interface

OpenAGC uses a state-of-the-art graphics display system running under X/MOTIF or Microsoft Windows NT. A series of highly effective tabular displays and graphic plots/trends serve as the operator user interface.

Interoperability

OpenAGC can run on PCs or RISC-based workstations under a Microsoft Windows NT or UNIX/MOTIF environment.
