Improving Electrical Grid Operations (478)

Problem: Understand and manage the electrical distribution grid to maximize system utilization capability and minimize outages.

Project Activity Scope (from Electronics Technology Overview Chart): Interaction Mechanisms through Integrated Systems

PNNL Solution:

• Developed system analysis and control tools to allow reliable grid operation with high utilization factors
  • Developed tools to analyze operating grid data to rapidly identify stability problems and corrective options
  • Improved operator response by detailing corrective action options
  • Developed training sets to improve operator response to future events
• Evaluated and validated tool performance in PNNL's Electricity Infrastructure Operations Center (EIOC)

Capabilities Employed to Meet Client Needs: Power system dynamics analysis, development and applications of power system simulation algorithms, study of electric economics impact on power system operation, market simulation, use of major power system simulation software including Positive Sequence Load Flow (PSLF) software from General Electric, Power System Simulator for Engineering (PSS/E) from Power Technologies International, and HABITAT/DTS (AREVA T&D), modeling of renewable energy and smart grid deployment, development of distribution system simulator and system identification toolbox, deregulation and restructuring, power system modeling, software development, data acquisition and interpretation.
